Hair Extensions

Hair extensions add length, volume or a splash of colour by attaching strands of human or synthetic hair to your own. There are several methods, and the right one depends on your hair type, lifestyle and budget. Temporary clip-ins go in and out at home, while semi-permanent options are fitted in a salon: tape-in wefts, individual keratin or pre-bonded strands, and micro, nano or ceramic rings that clamp small sections without heat or glue. Weaves and hand-tied wefts are sewn onto braided rows. Each method carries its own care routine and lasts anywhere from a few weeks to several months before repositioning is needed as your natural hair grows. Good extensions, fitted well and looked after, can look and feel natural. The main thing to understand is that extensions place ongoing weight and tension on your own hair and scalp, so skilled fitting, sensible weight and honest aftercare matter as much as the hair itself. A reputable stylist will assess whether your hair is strong enough, match colour and texture carefully, and be upfront about maintenance and cost so you can decide whether extensions genuinely suit you.

Start with a consultation before booking a full fitting, ideally with the hair in its natural, clean state so the stylist can assess density, condition and scalp health and recommend a suitable method and weight. Be honest about any hair loss, thinning, recent illness, medication or scalp conditions, as these affect whether extensions are advisable and which method is kindest. Discuss colour matching, length and how the result can be tailored, from subtle volume to dramatic length, and ask to see the hair being used. In the days before, wash and dry your hair as instructed, usually clean and product-free so bonds or rings grip well. Avoid heavy conditioners or oils on the roots on the day. It is worth clarifying the full cost, expected lifespan, maintenance appointments and removal in advance, since extensions are an ongoing commitment rather than a one-off. If you colour your hair, do this beforehand so the extensions can be matched to the finished shade.

Fitting time varies with the method and the amount of hair, from around one hour for tapes to several hours for a full head of individual bonds or a hand-tied weave. Your stylist will section the hair and attach the extensions close to, but not tight against, the scalp, leaving a small gap so the roots can move naturally. Tape-ins sandwich thin wefts against sections of your own hair; ring or bead methods thread small sections through a bead and clamp it; keratin bonds are fused with a heated tool; wefts are sewn onto braids. You may feel gentle pulling, pressure or the warmth of a bonding tool, but fitting should not be painful. Once in, the extensions are cut and blended into your own hair and styled so the join sits invisibly. A good stylist checks the tension feels comfortable before you leave and shows you how everything should sit, then talks you through brushing, washing and sleeping so you leave knowing exactly how to care for them.

Wait as advised, often 24 to 48 hours, before washing so bonds or tapes settle. Use sulphate-free, extension-friendly shampoo and conditioner, wash gently in a downward motion and keep conditioner and oils away from the roots and bonds. Brush daily with a soft extension or loop brush, starting at the ends and working up while holding the roots to avoid tugging the attachments. Always dry the roots and any bonds fully, as leaving them damp can cause slippage, matting or odour. Tie hair loosely in a plait or low ponytail before bed and consider a silk pillowcase to reduce tangling. Use heat protectant and keep straighteners and dryers away from the bonds themselves. Book maintenance appointments on schedule so extensions are moved down or refitted as your hair grows, and never pull extensions out yourself. If anything feels tight, sore or itchy, contact your stylist promptly rather than waiting.

The biggest risk with extensions is traction alopecia, hair loss caused by prolonged tension pulling on the follicles, which the British Association of Dermatologists notes can become permanent if repeated over time. Choosing an experienced, insured stylist who fits at a sensible weight, leaves the roots free to move and does not overload fine hair is the single most important safeguard. Tools that touch multiple clients, such as pliers, should be clean, and any hair used should be from a reputable source. Extensions are not suitable for everyone; if your hair is already fine, fragile or thinning, added weight can accelerate loss, so a good stylist will say so honestly. Never leave semi-permanent extensions in beyond the recommended time, as overgrown bonds tangle at the root and are harder to remove safely. Removal should always be done by a professional using the correct products, never pulled or cut out, to protect your own hair.

Extensions are a cosmetic service rather than a medical treatment, but some health factors matter. If you are experiencing hair loss, thinning, a flaky or inflamed scalp, or any scalp condition such as psoriasis or dermatitis, speak to your GP, a dermatologist or a trichologist before adding extensions, as tension may worsen the underlying issue. Hair can shed more than usual after pregnancy, illness, significant stress or certain medications, and this is not always the best time to add weight. People with very fine or chemically over-processed hair may not be suitable candidates. If you have a scalp allergy or sensitivity, or react to adhesives, mention this so any glue or bonded method can be avoided or tested. Anyone noticing patches of thinning, a receding hairline at the temples or sore, tender spots where extensions attach should have them removed and seek advice, as early action gives the best chance of the hair recovering.

A skin patch test is not usually required for the common methods, since ring, bead and tape systems involve no colour developer or reactive chemicals. The key pre-treatment check is a proper consultation and, ideally, a strand or trial test where the stylist assesses your hair's strength, density and scalp health and confirms it can carry the chosen weight. If a glue or bonded adhesive method is used, or the extensions will be tinted or toned to match, a patch test for that specific product is sensible to reduce the small risk of an allergic reaction. This consultation matters for liability too: an insured stylist who assesses suitability and documents it, and declines to fit where hair is too fragile, is protecting both you and their standing should a problem arise. Skipping that assessment leaves both of you exposed.

Be cautious if a stylist does not ask about your hair history or check your scalp, cannot tell you what hair they use or where it comes from, or has no insurance. Extensions fitted so tightly that your scalp feels sore, or that leave you with a persistent headache, tenderness or small bumps at the roots, are a warning sign of excessive tension and possible traction damage. Attaching heavy extensions to fine or clearly thinning hair, or fitting bonds right against the scalp with no room to move, is poor practice. Vague or missing aftercare advice, no plan for maintenance and removal, pressure to book on the spot, and prices that seem too good to be true are all reasons to pause. Any redness, itching, weeping or bald patches after fitting should be checked promptly.

A good stylist starts with an unhurried consultation, examines your hair and scalp and is honest about whether extensions suit you, even if that means saying no. They explain the method options, match colour and texture carefully, and fit at a weight and tension your own hair can comfortably support with the roots left free to move. They use hair from a reputable source, keep tools clean, and check the tension feels right before you leave. Clear, written aftercare, a realistic maintenance schedule and upfront pricing that includes repositioning and removal are all signs of professionalism. They hold appropriate training and insurance, welcome your questions, and encourage you to come back if anything feels tight or uncomfortable rather than leaving you to manage alone.

Which method do you recommend for my hair type and condition, and why?
What hair do you use, where is it sourced, and is it human or synthetic?
How much weight will you fit, and is my hair strong enough to carry it safely?
How often will I need maintenance appointments, and what does the full cost include?
How are the extensions removed, and is removal included in the price?
Are you trained and insured for this method, and what happens if I have a problem?

During fitting you may feel gentle tugging, pressure or clamping as sections are secured, and a little warmth from a bonding tool with keratin methods, but none of it should hurt. Afterwards it is normal to feel slightly aware of the extra weight and a mild tightness at the roots for the first day or so, especially when you tie your hair up or lie down, as your scalp adjusts. This settling feeling should ease quickly and stay comfortable. What you should not feel is ongoing soreness, stinging, throbbing or persistent tightness; those signal too much tension and are worth reporting to your stylist rather than tolerating.

There is no real downtime and you can return to normal activities straight away. In the first day or two your scalp may feel slightly tender or aware of the added weight as it adjusts, which usually settles quickly. Some people notice mild tightness at first; this should ease within a day and never be painful. Swimming, saunas and vigorous exercise may need extra care to protect the bonds, so check with your stylist. If tenderness, itching or soreness persists beyond the first couple of days, or you notice small bumps or sore spots at the roots, get the tension checked, as extensions should feel comfortable to wear.

Results are immediate, giving added length, volume or colour that, fitted well, blends naturally with your own hair. How long they last depends on the method and how fast your hair grows: tapes and bonds typically need repositioning every six to eight weeks, ring and bead methods around every eight to ten weeks, and clip-ins simply come out each night. Extensions do not stop your natural hair growing, so bonds gradually move away from the scalp and must be moved up or refitted to stay comfortable and tangle-free. Good daily care, gentle brushing, extension-friendly products and protecting the hair at night, will keep them looking their best and can extend the life of the hair itself, which may be reused across several fittings depending on quality. Building in rest periods without extensions from time to time gives your natural hair and scalp a chance to recover, which most stylists will encourage.

Colour Correction

Colour correction is specialist hair colouring that puts right a colour result you are not happy with, or takes hair from one place to a very different one. It covers a lot of ground: lifting out a box dye that has gone too dark, removing bands of uneven colour, neutralising brassy, green or orange tones, blending grown-out highlights, or moving from dark to a much lighter blonde. Because it often means removing existing pigment as well as adding new, it usually involves several processes in one visit, and sometimes across more than one appointment. It leans heavily on a colourist's understanding of colour theory and on the current condition of your hair, since bleach and colour removers ask a lot of the hair's structure. A good colourist works to a realistic plan that protects the integrity of your hair, even if that means getting to your goal in stages rather than all at once. The right approach, shade and level of change are always tailored to what you want, what your hair can safely take, and how much upkeep you are happy to commit to afterwards. It is skilled, time-consuming work, so honest expectations matter from the start.

Book a consultation before the appointment itself, ideally in person, so the colourist can see and feel your hair, discuss your history and set realistic goals. Be completely honest about everything that has been on your hair, including box dyes, henna, previous bleach, toners and home kits, because some products (henna and metallic salts in particular) can react badly with professional colour and cause heat or breakage. Bring photos of what you are hoping for and of your natural or previous colour. Arrange an allergy alert test at least 48 hours beforehand if any product involved contains dye, and expect a strand or incompatibility test on a small section to check how your hair will lift and hold up. Come with hair in reasonable condition; your colourist may suggest conditioning treatments beforehand. Avoid washing right before if advised, and set aside plenty of time, as correction can run from a couple of hours to most of a day.

Your colourist will start by reassessing your hair and confirming the plan, then work through the correction in stages. Depending on what is needed, this can involve a colour remover or bleach to lift out unwanted pigment, followed by cleansing, then the application of your target shade and a toner to refine the result. Sections are usually worked methodically, sometimes with foils or a balayage technique, and your colourist will keep checking how the hair is lifting and how it feels, adjusting as they go to protect its condition. Bond-building or strengthening additives are often used to support the hair through the process. There will be periods of development time under supervision, several washes at the basin, and often a treatment mask at the end. It is normal for this to take a long time and to feel like a slow, careful job rather than a single application. For big changes, your colourist may stop at a safe point and book you back to continue another day.

Colour-treated and freshly lifted hair needs gentle, consistent care to keep both the tone and the condition. Use a sulphate-free, colour-safe shampoo and conditioner, and try to leave the first wash for a couple of days if your colourist advises it, so the colour settles. Wash a little less often and with cooler water, as hot water and frequent washing fade tone faster. Use a weekly bond-building or deep-conditioning mask, and a toning or purple product if you have gone blonde and want to hold off brassiness. Protect hair from heat with a heat-protectant spray and keep styling tools at a moderate temperature, since processed hair is more fragile. Sun, chlorine and salt water can all shift colour and dry hair out, so rinse after swimming and consider UV protection. Book any recommended follow-up toning or treatment appointments, and keep up with trims to manage any dryness at the ends.

The two big safety points are protecting your skin and scalp from an allergic reaction, and protecting your hair from over-processing. In the UK, an allergy alert test should be carried out at least 48 hours before any service involving hair dye, following the manufacturer's instructions, and never skipped for new clients or when products change. Just as important with correction is the incompatibility and strand test, which checks whether your hair holds hidden products like henna or metallic salts that can react violently with bleach, and how well the hair will lift without breaking. A skilled colourist will refuse or slow down a service if the hair is not strong enough, and will build the change in stages rather than pushing hair to breaking point in one sitting. Bond-building additives, careful timing and constant monitoring all reduce risk. Choose an experienced, insured colourist who is honest about what is safe, even when that is not what you were hoping to hear.

Hair colour is a chemical treatment, so a few health matters are worth raising at consultation. If you have ever had a reaction to hair dye, temporary black henna tattoos or products containing PPD (paraphenylenediamine), tell your colourist, as this signals a real risk of a serious allergic reaction and colour may not be safe for you. Flag any scalp conditions, psoriasis, eczema, open cuts, recent scalp treatments or extreme sensitivity, since colour should not go onto broken or inflamed skin. Mention pregnancy or breastfeeding; while there is no strong evidence that professional colour is harmful, many salons take a cautious approach and may adjust timing or technique, and you may prefer to check with your midwife or GP. Certain medications and health conditions can affect the scalp or hair, so share anything relevant. If you have any signs of a reaction such as swelling, a spreading rash, itching or difficulty breathing after a test or service, seek medical help promptly and contact your GP or NHS 111.

Yes, a skin patch test, known in the trade as an allergy alert test, is standard and important whenever a service involves hair dye. It should be done at least 48 hours before the appointment, following the specific product manufacturer's instructions, because reactions can take up to two days to show. In the UK this matters for liability as much as safety: if a client reacts and no valid test was carried out, an otherwise insured salon can be found at fault, and many insurers require testing records to be kept. It is worth understanding that a patch test is not a cast-iron guarantee; sensitivities can build up over time, so a past clear test does not mean you can never react. For correction specifically, expect an additional strand and incompatibility test on a hidden section, which checks how your hair will lift and whether it holds any products that could react dangerously with bleach or colour remover.

Be cautious if a colourist promises to take you from very dark to bright blonde in one short sitting with no mention of hair condition, or dismisses the need for an allergy alert test or a strand test. Reluctance to discuss your colour history, or brushing off box dye or henna as unimportant, is a warning sign, since these can cause serious reactions with bleach. Watch out for anyone who ignores hair that is stretching, gumming or breaking during the process and simply carries on, or who leaves bleach on without checking it. Pushing you past what your hair can safely take, refusing to work in stages, no insurance, and vague or evasive answers about risks all suggest you should think again. A strong chemical smell of burning, scalp pain rather than mild warmth, or visible breakage are signs to stop.

Good practice starts with a proper consultation where the colourist looks at and feels your hair, asks about your full colour history, and sets honest, realistic expectations. Look for a clear plan, a willingness to work in stages across more than one visit if that protects your hair, and a straightforward explanation of costs and time. A responsible colourist insists on an allergy alert test at least 48 hours ahead and carries out a strand and incompatibility test before committing. Expect bond-building products, careful monitoring during development, and regular checks on how the hair feels. Clean tools, sensible use of gloves and barrier cream, good record-keeping, and up-to-date insurance are all reassuring. Above all, a colourist who is happy to say no, or not yet, when a change is not safe is showing exactly the judgement you want.

Based on my hair's history and condition, is my goal realistically achievable, and can it be done safely in one visit or will it need stages?
Will you carry out an allergy alert test and a strand or incompatibility test before we start, and how far in advance?
What processes will be involved, roughly how long will it take, and what will it cost including any follow-up appointments?
How will you protect my hair's condition during the process, and what do you do if the hair starts to struggle?
What will the upkeep be like at home, and which products and treatments do you recommend to keep the colour and condition?
Are you experienced in colour correction specifically, and do you hold current professional insurance?

During the service you can expect to feel the products being applied and worked through your hair, and some mild warmth on the scalp is normal, especially with lightening products, as they generate a little heat. It should never feel genuinely painful, burning or stinging; that is a sign to speak up straight away. You may notice a distinct smell from bleach or colour remover, and your scalp can feel slightly tingly or sensitive, particularly if colour goes near the roots. There is a lot of time at the basin with warm water and several washes, which most people find relaxing. Afterwards the hair itself may feel different in texture, sometimes a little drier or more squeaky-clean, until conditioning treatments settle it back down.

There is no downtime in the medical sense; you can carry on with your day straight afterwards. The main recovery is for the hair itself, which may feel drier or more porous for a while after heavier lifting and benefits from a run of conditioning treatments. Tone can settle over the first week or two, so the exact shade may soften slightly after the first few washes. If your goal needs more than one session, there will be a planned gap of a few weeks between appointments to let the hair rest and recover before further processing, which is a sign of responsible practice rather than a delay.

Results vary hugely with correction, from a subtle tonal fix to a dramatic change of level, and the more ambitious the goal the more upkeep it tends to need. Fashion tones, blondes and anything that involves lifting will usually fade or shift over the weeks and need periodic toning to stay looking fresh, while regrowth means roots will show as your hair grows, typically prompting a maintenance visit every few weeks to a couple of months. Looking after the colour at home with colour-safe, gentle products and regular conditioning makes a real difference to how long it lasts and how healthy it stays. Be prepared that a full correction can be an ongoing relationship with your colourist rather than a one-off; big changes are often reached and then maintained over several appointments. Trims help keep processed ends in good shape, and being realistic about maintenance from the start helps you choose a result you will be happy to keep up.

Keratin Treatment / Brazilian Blowout (Hair Smoothing)

Keratin treatments and the Brazilian Blowout are semi-permanent hair-smoothing services that coat and bond a protein-based solution to the hair, which is then sealed with a flat iron. The aim is to reduce frizz, add shine and make hair easier to blow-dry and manage, rather than to permanently straighten it. Results are temporary and gradually wash out over roughly three to six months. The most important thing to understand is that some traditional smoothing products contain, or release, formaldehyde when heated, which is a recognised irritant and, at higher levels or with repeated exposure, a health concern for both clients and stylists. For this reason many reputable UK salons now use lower-risk, so-called formaldehyde-free systems based on ingredients such as glyoxylic acid, carbocysteine or amino acid complexes, though the smoothing effect and longevity can differ. The finish can be tailored, from a soft frizz-reduction that keeps some natural movement to a sleeker, straighter result, depending on the product, the number of passes with the iron and your hair type. A good salon will assess your hair and history first and be open about exactly which product they use and why.

Book a consultation before your appointment so the stylist can assess your hair type, condition and any recent chemical services such as colour, bleach or other straightening treatments, as these affect suitability and the result. Ask which specific product will be used and request the Safety Data Sheet, as this shows whether the formula contains or releases formaldehyde and confirms it is being used correctly. Tell the salon if you are pregnant or breastfeeding, have asthma or a history of reacting to fumes, or have any scalp condition such as eczema, psoriasis or recent broken skin, as these may mean the treatment is not right for you. Come with clean, product-free hair unless told otherwise, and avoid colouring on the same day unless the salon advises the order. A strand test on a small section can help predict how your hair will respond. Make sure the salon is well ventilated, and raise any concerns openly beforehand rather than on the day.

Expect the appointment to take around one and a half to three hours or more, depending on hair length and thickness. Your hair is usually washed with a clarifying shampoo to open the cuticle, then the smoothing solution is applied section by section and combed through. After a processing period the hair is blow-dried and sealed with a flat iron at high temperature, which is the stage that locks in the smoothing effect and, with formaldehyde-containing products, is when fumes are most likely to be released. You should notice good ventilation, and the stylist may wear a mask; if the room feels stuffy or your eyes, nose or throat start to sting, say so, as this can indicate formaldehyde in the air. The process is not usually painful, though the chemical smell and the heat near your scalp can feel intense. Your stylist can adjust the number of iron passes to give you a softer or sleeker finish to suit your hair and preference.

Aftercare has a big influence on how long your results last. With many traditional keratin treatments you are advised to keep the hair dry, loose and unclipped for the first few days, typically up to seventy-two hours, avoiding washing, tying it back, tucking it behind your ears or using clips or hairbands that could leave a mark. Some newer formaldehyde-free systems allow washing sooner, so always follow the specific instructions your stylist gives you. After the settling period, use a sulphate-free and sodium-chloride-free shampoo and conditioner to protect the treatment, and wash less often, ideally two to three times a week. Chlorine and salt water can strip the smoothing effect, so wear a swim cap or apply a leave-in conditioner before swimming, and consider a hat in strong sun. Heat styling can be reduced but is not usually banned. If your scalp becomes irritated, itchy or sore afterwards, stop and seek advice from a GP or pharmacist.

The single most important safety issue with hair smoothing is formaldehyde, which can be released as a gas when the product is heated with a flat iron. It is a known irritant and is classed as a carcinogen at higher levels or with repeated exposure, which is why good practice centres on knowing what is in the product and controlling the fumes. Ask to see the Safety Data Sheet and choose a salon that is transparent about its formula and uses lower-risk or so-called formaldehyde-free options where possible. Note that some formaldehyde-free products can still release small amounts when heated, so ventilation matters regardless. The room should have good airflow or extraction, and the stylist should follow the manufacturer's temperature and timing instructions. Under UK workplace health and safety rules, salons should assess and manage these chemical risks for staff and clients. If you experience burning eyes, a stinging throat or breathing difficulty during treatment, ask them to stop and step into fresh air.

Hair smoothing is a cosmetic service, not a medical one, but there are health situations where it is best avoided or delayed. Many salons and product makers advise against treatment during pregnancy or breastfeeding as a precaution, largely because of possible formaldehyde exposure, and it is sensible to discuss this with your midwife or GP. People with asthma or other respiratory conditions may be more sensitive to fumes and should take particular care over ventilation and product choice. Active scalp conditions such as eczema, psoriasis, dermatitis or broken or inflamed skin can be aggravated, so treatment is usually postponed until the skin has healed. If you have had a previous reaction to hair products or chemical fumes, tell the salon and consider seeking advice first. This information is general and not a substitute for personalised guidance; if you have any health concern, or symptoms that persist after treatment, speak to a GP or pharmacist.

A traditional allergy patch test is not the standard check for hair smoothing in the way it is for hair colour, but a proper pre-treatment consultation is important and, done well, protects both you and the salon. The stylist should review your hair condition, recent chemical services and any medical or scalp issues, and ideally carry out a strand test on a small section to see how your hair reacts and how straight it goes. This helps set realistic expectations and reduces the risk of damage or a poor result. From a UK liability point of view, a salon that skips consultation and testing and records nothing can more easily be found at fault if something goes wrong. If your particular product carries a manufacturer instruction to patch test, that should always be followed, as should the guidance to check for skin sensitivity before use.

Be cautious if a salon cannot or will not tell you which product they use or provide its Safety Data Sheet, or dismisses your questions about formaldehyde. A poorly ventilated, stuffy room with no extraction, and no willingness to open windows or use fans during the flat-ironing stage, is a warning sign, as is a strong chemical smell that makes your eyes water or throat sting while the stylist offers no protection. Treatments marketed as completely safe with no possible downsides, or pushed on you during pregnancy without caution, should raise doubt. Other concerns include no consultation or strand test, no questions about your medical history or previous chemical services, pressure to book on the spot, and prices that seem too good to be true. Trust your instincts and leave if you feel unwell.

A trustworthy salon is open about exactly which product it uses and will happily share the Safety Data Sheet and explain whether it contains or releases formaldehyde. Good practice includes a proper consultation that reviews your hair condition, previous chemical treatments and any health or scalp issues, along with a strand test where helpful. The treatment space should be well ventilated, with fans or extraction, and the stylist may wear a mask during the heat-sealing stage. Look for clear, honest advice about what the treatment can and cannot do, realistic estimates of how long results last, and detailed written aftercare. Experienced, trained stylists who are comfortable tailoring the finish to your hair, who follow the manufacturer's temperature and timing instructions, and who carry appropriate insurance are all reassuring signs of a responsible salon.

Which specific smoothing product do you use, and can I see its Safety Data Sheet?
Does it contain or release formaldehyde when heated, and if not, what is the active ingredient instead?
How is the room ventilated during the flat-ironing stage?
Will you do a consultation and a strand test to check how my hair will respond?
Is this treatment suitable given my hair history, and is there any reason I should avoid it?
How long should the results last for my hair type, and what aftercare do I need to follow?

During the treatment you can expect to notice a strong chemical smell and warmth near the scalp as the flat iron seals the product in. The process itself is not usually painful, and many people find it relaxing apart from the odour. Some clients feel mild tingling on the scalp. What you should not simply put up with is stinging or watering eyes, a burning sensation in the nose or throat, coughing or any tightness in the chest, as these can be signs of formaldehyde in the air and are a reason to pause, ventilate the room and step outside for fresh air. Afterwards the hair usually feels noticeably smoother, sleeker and easier to manage, and any faint product smell tends to fade after the first wash.

There is generally no recovery time, and most people return to normal activities straight away. The main limitation is the settling period some products require, when the hair must stay dry and unmarked for up to seventy-two hours, so it helps to plan around exercise, swimming and washing. If you inhaled fumes during the treatment and feel mild eye, nose, throat or chest irritation, this typically eases in fresh air, but persistent coughing, wheezing, headaches or a skin reaction should be checked by a GP. Any lasting scalp soreness, redness or unusual hair breakage is worth reporting to the salon and a healthcare professional.

Hair smoothing gives a temporary result that gradually washes out rather than growing out in a hard line, so hair looks natural as it fades. Depending on the product and your hair, formaldehyde-free semi-permanent treatments often last around three to four months, while stronger systems such as a classic Brazilian Blowout may last four to six months. Longevity depends heavily on aftercare: using sulphate-free and salt-free products, washing less frequently, and protecting hair from chlorine, salt water and strong sun all help the effect last. The finish can be tailored at your appointment, from a soft reduction in frizz that keeps natural movement to a sleeker, straighter look. Bear in mind these treatments smooth and manage the hair rather than permanently altering the curl pattern, so your natural texture returns as the product wears off. Repeat treatments are possible, but avoid over-processing, and give your stylist a full history of any smoothing or straightening you have already had.

Electrolysis

Electrolysis is a method of permanent hair removal that treats one hair at a time. A very fine sterile probe is slid into the natural opening of the hair follicle, alongside the hair, and a tiny amount of energy is released to disable the cells responsible for regrowth. The hair is then eased out with tweezers. It is the only hair-removal method recognised by professional bodies as capable of permanently removing hair, and unlike laser or IPL it works on any hair colour, including grey, red, white and fair hair, and on all skin tones. Because each follicle is treated individually and hair grows in cycles, electrolysis is a course of treatments rather than a one-off, often spread over many months. It is commonly chosen for the face (upper lip, chin, jawline, brows), as well as underarms, breast area and stray body hairs, and it can be used to reduce hair linked to hormonal changes. Three techniques are used, usually described as galvanic, thermolysis (shortwave diathermy) and blend; a skilled practitioner selects the approach and adjusts the settings to suit your hair, skin and comfort. Results build gradually and can be tailored to full clearance or thinning.

Service

Electrolysis

Book a consultation first so your practitioner can look at the area, take a brief medical history and check nothing rules the treatment out. In the run-up, leave the hair alone in ways that pull it from the root: avoid tweezing, waxing, threading and epilating for at least a few weeks, as the follicle needs an intact hair to treat. Trimming or shaving between sessions is fine, and hair should be visible on the day so it can be found and treated. Keep the skin healthy and unbroken, avoid sunburn, fake tan and sunbeds beforehand, and stay well hydrated as this can make treatment more comfortable and effective. Tell your practitioner about any medicines, skin conditions, recent cosmetic procedures or changes to your health. If you are taking isotretinoin (Roaccutane), have used it recently, or take blood-thinning medication, mention this at booking, as it may mean waiting or seeking medical advice first.

You will usually lie back while the practitioner works under a good light, often with magnification. A fine, single-use sterile probe is gently inserted into the follicle opening alongside the hair; it should not pierce the skin. A small amount of energy is released for a moment, then the loosened hair is lifted out with tweezers, and the process is repeated hair by hair. You may feel brief warmth, a prickle or a stinging sensation as each follicle is treated, with more sensitive areas such as the upper lip tending to feel sharper. The practitioner can adjust the intensity, technique and timing to keep you comfortable and to protect your skin, so speak up if anything feels too strong. Session length depends on the size of the area and the amount of hair, from around ten or fifteen minutes for a small patch to longer for larger regions. Mild redness and slight swelling around the follicles during and just after treatment are normal.

For the first day or two the skin may look pink, feel warm or show tiny raised spots or scabs where follicles were treated; this settles on its own. Keep the area clean and avoid touching, scratching or picking, as this raises the risk of infection or marking, and let any small scabs fall away naturally. Skip make-up and heavy or perfumed products on the area for around 24 hours, and avoid heat and sweating from saunas, steam rooms, hot baths, swimming pools and vigorous exercise for the first day or so. Protect the area from strong sun for a few days and use a high-factor sunscreen once any reaction has calmed, which helps prevent pigment marks. A soothing, fragrance-free moisturiser or an aftercare product recommended by your practitioner can help. Between sessions, stick to trimming or shaving rather than tweezing or waxing, so there is an intact hair to treat next time.

The most important safety points are hygiene and skill, because the probe enters the follicle and treats skin very precisely. Choose a trained, insured electrologist, ideally a member of a recognised professional register, and check that they use fresh, single-use sterile probes and gloves, clean tweezers and good hand hygiene. In many parts of the UK, businesses offering skin-piercing style treatments must register with their local authority for hygiene, so it is reasonable to ask. Correct probe insertion, energy settings and technique matter: too much energy or poor technique can cause burns, marks or, rarely, scarring, so competence and a proper consultation are key. A good practitioner assesses your skin type and hair, works at a comfortable intensity, and paces the course sensibly rather than over-treating an area in one go. If anything about cleanliness, equipment or your comfort feels wrong, it is fine to pause and ask questions.

Electrolysis is not suitable for everyone, so an honest medical history matters. It is generally avoided over pacemakers and with certain heart conditions or uncontrolled high blood pressure, epilepsy, and uncontrolled diabetes, and it is not carried out on areas of active infection, cold sores, sunburn, broken skin, moles or unexplained lesions. Pregnancy, some skin conditions, a tendency to keloid scarring, and reduced immunity or conditions such as lupus may mean it is postponed or needs medical advice first. Blood-thinning medication can increase bruising, and isotretinoin (Roaccutane) makes skin fragile, so treatment is usually delayed until well after finishing it. Because unwanted or increased hair can sometimes reflect an underlying hormonal issue such as polycystic ovary syndrome, it is worth mentioning sudden or marked changes in hair growth to your GP, as electrolysis treats the hair but not the cause. If you are unsure whether treatment is right for you, check with your practitioner or GP before booking.

A skin patch test is not the standard step for electrolysis, as it does not use dyes or chemicals; instead the safeguard is a proper consultation and, often, a short test area. Before a full course, many practitioners treat a small patch to see how your skin reacts and heals, to gauge the right settings and your comfort, and to confirm the approach suits your skin and hair. This is also when they take your medical history and check for contraindications such as pacemakers, uncontrolled diabetes, pregnancy, skin infections, Roaccutane use or blood thinners. Approaching it this way reduces the risk of burns, marks or reactions and supports safe, tailored treatment. From a UK liability point of view, a documented consultation and test area help protect both you and an insured practitioner, and give a clear point to raise any concerns before committing to a course.

Be cautious if the practitioner reuses probes or does not open a fresh single-use sterile one in front of you, skips gloves or basic hygiene, or works in a visibly unclean setting. Other warning signs include no consultation or medical-history questions, brushing off contraindications such as a pacemaker, pregnancy or Roaccutane use, or pushing you into a long course without a test area. Settings that feel repeatedly painful, the probe piercing the skin rather than sliding into the follicle, or persistent burns, blistering, pinpoint scabbing beyond the follicle or lasting marks all suggest poor technique or excessive energy. Unwillingness to answer questions about training, insurance or aftercare is also a reason to walk away.

Good signs include a qualified, insured electrologist who is a member of a recognised professional body and, where required, registered with the local authority for hygiene. They give you a proper consultation, take a medical history, explain the technique and realistic timescales, and often carry out a small test area first. You should see fresh single-use sterile probes, clean tweezers, gloves and good hand hygiene, with treatment carried out under good light. A trustworthy practitioner adjusts the settings to keep you comfortable, checks in during treatment, paces the course sensibly rather than over-treating, and sends you away with clear aftercare advice. They are happy to answer questions about their training, insurance and what to expect, and are honest that results build gradually over a course.

What are your qualifications and professional memberships, and are you fully insured for electrolysis?
Do you use single-use sterile probes, and is your business registered with the local authority for hygiene where required?
Which technique do you recommend for my hair and skin, and why?
Will you do a consultation and a small test area before starting a full course?
Given my medical history and any medicines I take, is electrolysis suitable for me right now?
How many sessions and what sort of spacing and cost should I realistically expect for my area?

Most people describe electrolysis as a series of brief sensations rather than constant pain: a momentary warmth, a prickle, tingle or a short sharp sting as each follicle is treated. How it feels varies with the area, your skin and your own sensitivity, and sensitive spots like the upper lip and chin tend to feel more intense than the body. Because each hair is treated individually, larger areas involve many small sensations over the session. The practitioner can adjust the intensity and technique to keep you comfortable, so it should be tolerable rather than distressing; tell them if it feels too strong. Mild warmth, redness and a slightly tender feeling afterwards are normal and soon settle.

Electrolysis usually involves little to no time off, and most people return to their day straight away. Expect some redness, warmth and occasionally slight swelling or small scabs around the treated follicles, which typically fade within hours to a few days depending on your skin and the area worked on. Larger or more sensitive areas can look pinker for longer. Because the skin has been treated at follicle level, avoid heat, heavy make-up and sun in the first day or two to let it recover. If you notice spreading redness, increasing pain, weeping or signs of infection, contact your practitioner or GP.

Electrolysis permanently disables treated follicles, but because hair grows in cycles and only actively growing hairs respond well, it takes a planned course of sessions to work through an area. Many people start with regular appointments, often every week or two at first, then space them out as the hair reduces, with a full course commonly spanning many months to over a year depending on the area, hair density and the cause of the growth. As treatment progresses you should see hairs become finer and sparser and regrowth slow. Hormonal factors, such as those in polycystic ovary syndrome, the menopause or some medicines, can prompt new follicles to develop over time, so occasional top-ups may be needed even after clearance. Sticking to shaving or trimming between sessions, following aftercare and keeping to your recommended schedule gives the best, longest-lasting result, which can be aimed at full clearance or simply thinning to your preference.

Balayage

Balayage is a freehand hair-colouring technique in which lightener is hand-painted onto the surface of the hair, usually without foils, to create a soft, sun-kissed, graduated effect. The word comes from the French for "to sweep", which describes how the colourist sweeps product through chosen sections, keeping the roots deeper and building brightness towards the mid-lengths and ends. Because the regrowth is deliberately blended rather than blocky, balayage tends to grow out more gently than traditional foil highlights and can need fewer root visits, which many people find easier to live with. It is a bespoke, artistic process, so the placement, warmth and level of lift can all be tailored to your natural colour, skin tone and how bold or subtle you want the finish. Most balayage involves bleach or lightener, often followed by a toner or gloss to refine the shade, so it does change the condition of your hair and asks for a little ongoing care. A good colourist will talk through what is realistically achievable for your hair in one sitting, as very dark or previously coloured hair may need more than one appointment to reach a target shade safely.

Service

Balayage

In most cases it helps to arrive with your hair in its normal, healthy state rather than freshly washed on the day, as a little natural oil can protect the scalp during lightening. Avoid washing immediately beforehand unless your salon advises otherwise, and hold off on any harsh clarifying or DIY box colour in the weeks before, since previous colour, henna or metallic dyes can react unpredictably with bleach. Book a consultation, ideally with a photo of the look you want and honest details of your colour history, so the colourist can judge what is achievable in one visit. If you have had a patch test more than six months ago, or never with this salon, arrange a fresh one at least 48 hours ahead where a toner or tinted product will be used. Mention any recent illness, medication, pregnancy or scalp sensitivity, and come with realistic expectations about lift, as very dark hair rarely reaches pale blonde safely in a single session.

Your appointment usually starts with a consultation where the colourist checks your hair's condition, discusses the shade and placement, and confirms your patch test is in date. They will then hand-paint lightener onto selected sections, often working freehand without foils, though some use a mix of techniques or clingfilm to control the lift. The bleach is left to develop and monitored closely; you may sit for a while as it processes, and the colourist will check it repeatedly rather than leaving it to guesswork. Once the desired level is reached your hair is rinsed, and a toner, gloss or conditioning treatment is often applied to refine the tone and reduce brassiness. Expect the whole process to take anywhere from around two to four hours or more, depending on hair length, thickness and how much lift is needed. A finishing cut and blow-dry usually complete the look, letting you see the dimension before you leave.

To keep balayage looking fresh, wait a couple of days before your first wash so the colour can settle, then wash less often using lukewarm water and sulphate-free, colour-safe products. A purple or blue-toned shampoo used occasionally helps counter brassiness on blonde and lightened tones, but use it sparingly as overuse can leave a dull cast. Lightened hair is more porous, so weekly deep-conditioning masks and a bond-building or protein treatment help restore strength and shine. Always apply a heat protectant before straighteners, tongs or a hairdryer, and keep styling temperatures moderate. Chlorine, salt water and hard water can shift the tone, so rinse after swimming and consider a barrier product or a hat in strong sun, as UV fades colour. Regular trims keep the ends looking healthy. Your colourist can recommend a home routine suited to your exact shade and hair type, and a toning gloss between appointments can refresh the colour without full re-lightening.

Balayage uses bleach or lightener, which is a strong chemical process, so the biggest safeguards are a skilled, trained and insured colourist and honest communication about your hair. A patch test in date for any toner or tinted product is important, as is a strand test to check how your hair will lift and hold together, particularly if it has been coloured before. Lightener should never be applied over unknown box dye, henna or metallic salts without care, as these can cause heat, breakage or unexpected colour. A responsible colourist assesses your hair's strength, may decline or stage the service if reaching your goal in one visit would damage it, and monitors the bleach closely rather than over-processing to hit a shade. Overlapping bleach on already-lightened hair is a common cause of breakage, so trust a professional who prioritises hair integrity over an instant result. If your scalp stings sharply during processing, tell them straight away.

Balayage is a cosmetic hair service rather than a medical treatment, but a few health factors are worth flagging to your colourist. A known allergy to hair dye ingredients such as PPD or PTD, or to bleach, is a clear reason for caution, and a history of any reaction should be discussed before booking. Sensitive, broken or inflamed scalp skin, eczema or psoriasis flare-ups, and recent scalp procedures can all make lightening uncomfortable or unwise. Pregnancy is generally considered low risk for hair colour, but many people prefer to wait past the first trimester or focus on off-scalp techniques, and it is sensible to mention it. Certain medications and treatments, including some that affect the immune system, can alter how your skin reacts, so a fresh patch test matters. If you have had a previous allergic reaction to colour, or you are unsure whether a treatment is safe for you, speak to your GP or a qualified professional before going ahead rather than relying on a salon alone.

A skin patch test is strongly recommended whenever a toner, gloss or tinted product will be used, as these can contain PPD and related allergens, even though the lightener itself is painted off the scalp. Arrange the test at least 48 hours before your appointment; most salons treat it as valid for around six months and repeat it after any gap or change in your health. This is not just precaution but a real liability point in the UK: skipping a patch test can leave an insured salon found at fault if a client reacts, which is why professional colourists insist on it. Bear in mind a patch test is not fully conclusive, as sensitivities can build over time and a reaction can appear even after years of trouble-free colouring, so tell your colourist about any new itching, medication or illness. A strand test also checks how your hair will lift and cope.

Be cautious if a salon offers to lighten your hair with no consultation, skips or waves away a patch test when toner will be used, or promises to take very dark or previously box-dyed hair to pale blonde in one quick session regardless of condition. A colourist who ignores obvious breakage, applies bleach carelessly over already-lightened lengths, or leaves you unattended for long stretches without checking the development is not working safely. Sharp, burning scalp pain during processing, rather than mild warmth, is a warning sign that should be acted on immediately. Vague answers about their training, no insurance, dirty tools or reused mixing products, and pressure to go bolder than you are comfortable with are all reasons to pause. Trust your instincts if promised results sound too good for your hair's starting point.

A good sign is a thorough consultation where the colourist looks at your hair, asks about its colour history and health, and sets honest expectations about what is achievable in one visit. They confirm your patch test is in date, carry out a strand test where needed, and are happy to explain their training, insurance and the products they use. Look for someone who prioritises the condition of your hair, is willing to stage the process over more than one appointment to avoid damage, and offers bond-building or conditioning support. Clean tools, freshly mixed product, careful application and regular checking of the bleach all show good practice. A trustworthy professional will tailor the placement and tone to suit you, talk through realistic maintenance, and never pressure you into a result your hair cannot safely take.

Based on my hair's colour history and condition, what result is realistically achievable in one visit, and might it need more than one appointment?
Are you trained and insured for lightening and colour work, and how much experience do you have with balayage?
Do I need a patch test and a strand test before this, and when should I come in for them?
Will you be using a toner or gloss, and what ingredients such as PPD does it contain that I should be aware of?
How will you protect the condition of my hair, and do you offer bond-building or conditioning treatments?
What ongoing care, products and how often will I need appointments to keep this looking its best?

During balayage you can usually expect to feel the colourist painting product onto sections of your hair, which is painless, and then a period of sitting while the lightener develops. Because the bleach is often kept off the scalp, many people feel little more than mild warmth or a faint tingling as it works. Some slight scalp sensitivity or a cool sensation at the rinsing basin is normal, and the toner stage generally feels comfortable. What you should not feel is sharp stinging, burning or intense itching; if you do, tell your colourist straight away, as that is not part of a normal process. The appointment is long, so mild restlessness from sitting is more common than any real discomfort.

There is generally no downtime with balayage, and you can return to normal life straight away. The main thing to be aware of is that lightening changes the condition of your hair, so it may feel drier or more fragile at first and benefit from gentler handling and extra conditioning. If your scalp feels slightly tender after lightening this usually settles quickly, but any lasting soreness, itching, swelling or blistering is not normal and should prompt you to contact the salon and, if needed, seek medical advice. Otherwise, the adjustment is mostly about easing into a colour-friendly hair-care routine.

Balayage is designed to grow out softly, so you can often go longer between appointments than with foil highlights, typically stretching to several months before a refresh, depending on how much your natural colour contrasts with the lightened pieces. Many people book a toning gloss in between to keep the tone fresh without full re-lightening, and a full balayage top-up perhaps two to four times a year. The colour will gradually fade and can turn brassy as it does, which purple-toned products and salon toners help manage. Because lightened hair is more porous, its longevity depends a lot on your home care, so gentle washing, heat protection, deep conditioning and regular trims all help it last and stay in good condition. Your colourist can adjust brightness, placement and warmth at each visit to suit changing seasons or preferences, keeping the look tailored to you over time.

Brow Lamination

Brow lamination is a semi-permanent treatment that reshapes and sets your natural eyebrow hairs into a smoother, fuller, more uniform look. A gentle chemical lifting lotion softens the bonds within each hair so it can be brushed and held in a new direction, then a neutralising (or fixing) lotion resets those bonds to lock the shape in place. A nourishing serum usually finishes the treatment, and many salons offer an optional tint at the same time to add depth and definition. It suits unruly, sparse or downward-growing brows, giving a groomed, brushed-up effect without daily styling. The result is not permanent: it typically lasts around four to six weeks as your brow hairs naturally grow and shed. Because the lifting and neutralising lotions are active chemical products applied close to the eyes, brow lamination sits in the same care category as a lash lift or brow tint, so a proper patch test and consultation matter. The finish can be tailored to your preference, from a soft, natural groom to a bolder, fully brushed-up shape, so it is worth discussing the look you want with your therapist beforehand.

Service

Brow Lamination

Book a patch test at least 48 hours ahead if you have not had the exact products used on you recently, and keep any earlier date the salon offers. In the run-up, avoid picking up eye or skin irritation, and tell your therapist about recent brow tinting, waxing, threading or any active skin conditions around the brows. It helps to arrive with clean, product-free brows, as heavy makeup, oils and brow gels can affect how evenly the lotions work. If you use retinol, acids or other strong skincare near the brow area, pause these for a few days beforehand, as they can leave the skin more sensitive. Avoid sunbeds and heavy sun exposure just before. If you are pregnant, breastfeeding, prone to allergies or taking medication that affects your skin, mention this at consultation so your therapist can decide whether to proceed or adjust the treatment.

The treatment is relaxing and usually takes around 40 to 60 minutes with your eyes closed throughout. Your therapist starts by cleansing the brows and talking through the shape and finish you want, then combs the hairs into position. A lifting lotion is applied first to soften the hairs, left on for a timed few minutes and then removed, followed by a neutralising or fixing lotion that sets the new shape. If you have chosen a tint, this is applied next to add colour and definition. A nourishing serum is often smoothed on at the end to condition the hairs and calm the skin. You may notice a faint tingling or a slight product smell, but it should never sting or burn. Timings are important, so your therapist will watch the clock carefully, as leaving the lotions on too long can over-process and weaken the hairs. Do let them know straight away if anything feels uncomfortable.

The first 24 to 48 hours matter most, because the freshly set hairs need to stabilise. Keep your brows completely dry and avoid water, steam, saunas, swimming, hot showers and sweaty workouts during this window. Try not to touch, rub or pick at the brows, and skip makeup, cleansers, oils and creams over the area so the shape holds cleanly. After the first day or two you can gently brush the hairs into place each morning with a clean spoolie to keep them looking groomed. Because lamination is a lifting process, the hairs can feel drier than usual, so a nourishing brow or lash serum, or a little castor oil once healed, helps keep them conditioned and glossy. Use sunscreen or sunglasses if you are out in strong sun, as UV can fade a tint faster. If any redness, itching or irritation develops, stop applying products and contact your therapist or a pharmacist for advice.

The single most important safeguard is choosing a trained, insured brow therapist who patch tests and works hygienically. Brow lamination uses active chemical lotions very close to the eyes, so correct product choice and precise timing are what keep it safe and stop the hairs being over-processed. A good therapist takes a full consultation, checks for contraindications and never rushes or skips the patch test to fit you in sooner. The lotions should stay on the brow hairs and off the delicate eye area, and the treatment should be comfortable throughout, never burning or stinging. Overlapping treatments raise the risk, so brow tinting, lamination and waxing on the same brows need sensible spacing and professional judgement. If you have very fine, damaged or previously over-processed brows, a responsible therapist may advise against it or suggest waiting, because repeated or badly timed lamination can leave hairs brittle or frizzy. When in doubt, ask questions before you commit.

Brow lamination is a cosmetic treatment, not a medical one, but some circumstances mean it is safer to wait or seek advice first. Active eye infections, conjunctivitis, dermatitis, eczema, psoriasis or broken or irritated skin around the brows are reasons to postpone until the area has fully healed. If you have very sensitive skin, a history of reactions to hair dye, perms or cosmetics, or known allergies, flag this clearly, as the lifting lotions and tints can trigger sensitivities. There is limited evidence on chemical brow treatments during pregnancy and breastfeeding, so many therapists prefer to err on the side of caution and may ask you to check with your midwife or GP. Recent eye surgery, certain skin medications and treatments such as isotretinoin (Roaccutane) can also affect suitability. If you are unsure whether a health condition or medication is relevant, speak to your GP or pharmacist before booking, and always give your therapist an honest medical history.

Yes, a patch test is recommended, ideally at least 48 hours before every treatment, or before your first visit and again if the products or your circumstances change. A small amount of the lotions and any tint is applied, usually behind the ear or on the inner arm, to check for a reaction before they go near your eyes. In the UK this is as much about liability as comfort: if a therapist skips the patch test and a client reacts, their insurance may not cover the claim and they can be found at fault. It is worth knowing a patch test is not a cast-iron guarantee, as sensitivities can build up over time even after previous treatments passed without issue, which is why reputable salons repeat it. If you have ever reacted to hair dye or cosmetics, say so, and never let anyone talk you out of a patch test to save time.

Be cautious if a salon offers to skip the patch test so you can be seen sooner, cannot show training or insurance, or dismisses your questions about the products. Reused disposable tools, dirty brushes or a generally unhygienic space are clear warning signs. During the treatment, burning, sharp stinging or lotion running into your eyes is not normal and should stop the appointment. A therapist who leaves the lotions on far longer than the timings, or who pushes lamination on very fine, damaged or already over-processed brows without caution, is putting your hair at risk. Vague or over-the-top promises, such as permanently thicker brows or guaranteed results, are also a red flag. If anything feels rushed, unclean or dismissive of your comfort and safety, it is fine to pause or leave.

A good brow therapist offers a proper patch test and consultation, asks about your health, allergies and previous treatments, and talks through the shape and finish you want before starting. They work in a clean space with disposable or properly sanitised tools, apply the lotions carefully to the hairs and time each step precisely. They are trained, insured and happy to explain the products and answer questions without pressure. Honest advice is a strong sign, including telling you if your brows are too fine or fragile to laminate right now, or suggesting a gentler option. Clear aftercare guidance, realistic expectations about how long results last, and an invitation to get in touch if you have any concerns afterwards all point to a conscientious, professional service.

Are you trained and insured specifically for brow lamination, and how long have you been doing it?
Will you carry out a patch test before my treatment, and when should I come in for it?
Which products and brands do you use, and are they suitable for sensitive skin or allergies?
Do you think my brows are in good enough condition to laminate, or should I wait?
Can we discuss the shape and finish I want, and how natural or bold it will look?
What is the aftercare, and what should I do if I notice redness, itching or a reaction?

Brow lamination is generally comfortable and many people find it quite relaxing, as you lie with your eyes closed while your therapist works. You might feel a light tingling, coolness or a mild sensation of the lotions on the skin, along with a faint chemical or ammonia-like smell that soon passes. Gentle brushing and combing of the brows can feel pleasant. What you should not feel is any burning, sharp stinging or the lotions getting into your eyes, as that is a sign something is wrong. Everyone is different, so if you are sensitive or anything feels uncomfortable at any point, tell your therapist straight away so they can check and, if needed, remove the product.

There is usually no real downtime, and most people return to their day straight after. The main thing to respect is the 24 to 48 hour dry, hands-off period while the shape settles, as getting the brows wet or rubbing them too soon can cause them to lose their lift or look uneven. Any mild redness or tingling normally settles within a few hours. If you experience swelling, persistent itching or a rash, this may signal a reaction, so remove any products gently, avoid further irritation and seek advice from your therapist, a pharmacist or your GP, especially if it does not calm down.

Results are usually visible immediately, with brows looking fuller, neater and brushed into shape, and they typically last around four to six weeks as your natural hairs grow through and shed. In the first day or two the effect can look a little strong or defined, then it settles into a softer, more natural finish. To keep brows looking their best, brush them into place each morning with a spoolie and keep the hairs conditioned with a nourishing serum or oil, as lamination can leave them slightly drier. Most people repeat the treatment every four to six weeks, but it is best not to over-do it, because too-frequent lamination can leave hairs brittle or frizzy, and a good therapist will space appointments to protect your brow health. How dramatic or natural the result looks can be tailored to you, so let your therapist know if you prefer a softer groom, and mention if the previous finish was too much or too little so they can adjust next time.

Exosome Therapy (Skin and Hair)

Exosomes are microscopic extracellular vesicles that cells use to send signals to one another. In aesthetics, exosome-based products are used with the aim of supporting skin rejuvenation, texture and tone, and of encouraging a healthier scalp environment for hair. They are most often applied topically straight after microneedling, radiofrequency microneedling or a laser treatment, where the tiny channels created in the skin are intended to help the serum absorb. It is important to understand the UK legal position before you book. The medicines regulator (MHRA) treats injected exosomes as unlicensed medicinal products, and there is currently no exosome injectable with a UK marketing authorisation, so injecting exosomes cannot lawfully be offered here. Human-derived and stem-cell exosomes are not permitted for cosmetic use; only plant-derived or animal-derived exosome products used topically as cosmetics typically sit within the law. The evidence base is still young and results vary by product quality, so honest, realistic expectations matter. If a clinic offers to inject exosomes, that is a clear warning sign. Guidance in this area is evolving, so it is sensible to check the current position and choose an experienced, insured practitioner.

A thorough face-to-face consultation comes first, covering your skin or hair concerns, medical history, medications, allergies and what the treatment can realistically achieve. Because exosome serums are typically applied over microneedling or a similar device, your practitioner should confirm your skin barrier is healthy and intact. In the days beforehand it usually helps to pause retinoids, acids and strong exfoliants, and to avoid sunburn, active breakouts, cold sores or any skin infection in the treatment area. Tell your practitioner if you take blood-thinning medication, have had recent isotretinoin (Roaccutane), tend to form keloid scars, or are pregnant or breastfeeding, as these can affect suitability. Arrive with clean skin and no heavy make-up where possible. Ask to see the exosome product's packaging and ingredients so you can confirm it is a topical, plant-derived or animal-derived cosmetic rather than an injectable or human-derived product. Avoid alcohol immediately beforehand, as it can increase redness.

Your practitioner will cleanse the area and, in most cases, prepare the skin or scalp with a device that creates fine micro-channels, such as microneedling or radiofrequency microneedling. A superficial, comfortable microneedling depth should not draw blood; pinpoint bleeding or the routine use of numbing cream points to deeper, medical-depth work that belongs with a qualified medical practitioner. The exosome serum is then applied topically to the treated surface so it can absorb through the micro-channels, and some clinics finish with LED or a soothing mask. For hair, the serum is worked across the scalp in the areas of thinning. A face session commonly takes around 45 to 60 minutes including preparation. Throughout, a good practitioner will check your comfort, explain each step, and confirm the product being used is a topical cosmetic. You should not be offered an injection of exosomes, as this is not lawful in the UK.

For the first 24 hours the skin has been freshly needled, so treat it gently. Keep the area clean, avoid touching it with unwashed hands, and skip make-up, heavy serums and anything with acids, retinoids or fragrance until your practitioner says the barrier has settled, usually a day or two. Use a gentle cleanser and a simple moisturiser, and apply a broad-spectrum SPF each morning, as the skin is more sensitive to sun. Avoid saunas, steam rooms, hot yoga, swimming pools and vigorous exercise for a day or so, as heat and sweat can irritate freshly treated skin. For scalp treatments, delay hair washing for the time your practitioner advises and avoid harsh styling products. Follow the specific aftercare card you are given, and contact your clinic promptly if you notice spreading redness, increasing pain, pus or any sign of infection so it can be assessed.

The most important safety point is the UK legal position. Injecting exosomes is not lawful here because there is no licensed exosome injectable, and human-derived or stem-cell exosomes are not permitted for cosmetic use, so a responsible clinic offers only a topical, plant-derived or animal-derived cosmetic product. Because the treatment almost always involves needling, hygiene is essential: single-use, sterile needle cartridges, clean hands and gloves, and a properly cleaned treatment area reduce the risk of infection. Choose a practitioner who is trained, experienced and insured for this specific treatment, and be aware that standard policies may not cover exosomes, so it is fair to ask. A face-to-face consultation and honest discussion of the limited evidence should always come before treatment. Avoid clinics making bold curative or anti-ageing claims, offering injections, or unable to show you the product they use. When in doubt, ask your GP or a suitably qualified medical practitioner.

Although the product is applied topically, the needling step means suitability still needs checking. Treatment is generally avoided over active acne, eczema, psoriasis flares, cold sores, warts or any skin infection in the area, and on skin that is not healthy and intact. Tell your practitioner if you are pregnant or breastfeeding, take blood-thinning medication, have a bleeding disorder, are prone to keloid or raised scarring, have had recent isotretinoin (Roaccutane), or have a condition or medication that affects healing or immunity, as these can make the treatment unsuitable or need medical input. Anyone with a history of significant allergies should discuss the specific product ingredients. Exosome therapy is a cosmetic treatment, not a medical cure, and should not replace advice or care for hair loss or skin conditions with an underlying medical cause. If you are unsure, speak to your GP or a qualified medical practitioner before booking, particularly where hair loss may signal an underlying health issue worth investigating.

A skin patch test is not the routine standard for exosome therapy, but a careful pre-treatment consultation and contraindication check is essential and protects both you and the practitioner. Your practitioner should review your medical history, medications, allergies, skin condition and healing tendency, and confirm the treatment area is healthy before any needling. Because the serum is a specific cosmetic product, flag any known ingredient sensitivities, and ask your practitioner whether a small test application is sensible for reactive skin. Documenting this discussion and gaining informed consent matters for UK liability: skipping proper checks can leave an insured practitioner found at fault if a problem arises. Sensitivities can also develop over time, so an uneventful earlier session does not guarantee future ones, and any new reaction should be reported.

The clearest red flag is a clinic offering to inject exosomes, or promoting human-derived or stem-cell exosomes, as neither is lawful for cosmetic use in the UK. Be wary of anyone who cannot show you the product packaging and ingredients, or who makes strong curative or guaranteed anti-ageing claims. Other warning signs include no proper consultation or medical history, no written consent, and reused or non-sterile needle cartridges. Routine use of strong numbing cream in a non-medical setting suggests deeper, medical-depth needling beyond that setting's scope and raises real insurance and safety questions. Pressure to pay upfront for large courses, vague answers about training or insurance, and dismissal of your questions are all reasons to pause and look elsewhere.

Good practice starts with a genuine face-to-face consultation, a full medical history and honest, realistic talk about the still-developing evidence. A trustworthy practitioner uses only a topical, plant-derived or animal-derived cosmetic exosome product, will happily show you the packaging and ingredients, and never offers to inject exosomes. Look for clean, professional premises, single-use sterile needle cartridges, gloves and proper hygiene, and clear written consent and aftercare. They should be appropriately trained, experienced and insured for this specific treatment, and able to explain their qualifications. Sensible pricing without pressure to buy large courses, willingness to answer every question, and clear guidance on what results you can and cannot expect are all signs you are in safe hands.

Is the exosome product you use topical and plant-derived or animal-derived, and can I see the packaging and ingredients?
You will not be injecting the exosomes, since that is not lawful in the UK, is that correct?
What are your qualifications and experience with this treatment, and are you specifically insured for it?
How is the skin prepared, and will you use single-use, sterile needle cartridges?
What results can I realistically expect, how many sessions might I need, and what does the evidence actually show?
What aftercare will I need, and who do I contact if I have a reaction or concern afterwards?

During the needling step most people feel a light scratching or prickling sensation and some warmth, which is usually well tolerated at a superficial, comfortable depth. When the exosome serum is applied you may notice a cool, soothing feeling or mild stinging on freshly treated skin. Afterwards the skin often feels warm, tight and a little sensitive, much like mild sunburn, and may look flushed for a day or two. A scalp treatment can feel tender and tingly. Sharp pain, significant bleeding or the need for strong numbing cream are not expected with a standard superficial treatment and suggest deeper work that belongs with a qualified medical practitioner.

Downtime is usually short. Because the serum is applied over freshly needled skin, most people have redness and a warm, slightly tight feeling similar to mild sunburn for around 24 to 48 hours, sometimes with light flaking as the skin settles. Many return to everyday activities the same or next day, though it is wise to plan treatments a few days before an important event rather than the night before. Scalp treatments may feel tender for a day. Sensitive or reactive skin can stay pink for a little longer. If redness spreads, worsens or is accompanied by pain or discharge, contact your clinic, as this is not typical.

Results tend to appear gradually rather than overnight, as any benefit relies on the skin's own renewal over the following weeks. Many people are offered a short course of sessions spaced a few weeks apart, followed by occasional maintenance, and outcomes vary considerably depending on the product's quality and your skin or hair concern. It is honest to say the clinical evidence for exosomes is still emerging, so expectations should be modest and improvements are best described as supportive rather than dramatic or permanent. Good skincare, sun protection and a healthy lifestyle help any gains last. For hair, exosome therapy is not a cure for hair loss and works best as part of a wider plan discussed with a qualified practitioner or your GP, especially where an underlying medical cause may be involved. Your practitioner should review your progress and adjust the plan to suit you.
