Lowlights

Lowlights are a hair colouring technique that weaves darker shades through the hair to add depth, richness and dimension. Where highlights lift sections to a lighter tone, lowlights do the opposite, introducing deeper strands that create contrast and a natural, multi-tonal finish. They are often used to soften an over-lightened look, restore warmth to hair that has become flat or brassy, or give fine hair the appearance of more density. A stylist typically applies the colour to selected sections using foils, or hand-paints it through the hair for a softer, more blended balayage-style effect. The shades chosen usually sit a level or two below your base colour or existing highlights, and the intensity can be tailored from a subtle, barely-there depth to a bold, defined contrast depending on the look you want. Lowlights suit most hair types and are generally low-risk, though because permanent and semi-permanent colours contain dyes that can cause allergic reactions, an allergy alert test before your appointment is an important safeguard. A good stylist will discuss your hair history, condition and goals first so the result flatters your natural colouring and is realistic to maintain.

Service

Lowlights

Book a consultation before your appointment so your stylist can look at your hair's condition, natural level and any previous colour, and agree the shades and placement with you. Where colour products containing dyes such as PPD are being used, an allergy alert test should be carried out in good time beforehand, typically at least 48 hours ahead, even if you have been coloured before, because sensitivities can develop over time. Arrive with your hair in its usual condition unless your stylist advises otherwise; you generally do not need to wash it immediately before, as natural oils can help protect the scalp. Avoid using heavy styling products on the day. If you have recently used henna, box dye or a colour remover, tell your stylist, as these can affect how the colour takes. Bring photos of the depth and effect you are hoping for, and mention any medication, scalp conditions or past reactions to hair colour so the approach can be adjusted for you.

Your stylist will usually begin by confirming the shades and reviewing where the lowlights will sit to give the balance and contrast you discussed. Your hair is sectioned, and the darker colour is applied to selected strands, either wrapped in foils for precise placement or hand-painted through the hair for a softer, more blended finish. The colour is then left to develop for a set time, which varies with the products used and the depth being achieved. During this stage you can typically relax, and your stylist may check the colour's progress as it develops. Once ready, the colour is rinsed out, and a toner or gloss may be applied to refine the tone and add shine. A conditioning treatment often follows, and your hair is then blow-dried and styled so you can see the result. Depending on how many sections are being coloured, expect the appointment to take anywhere from around an hour to a few hours.

To keep your lowlights looking their best, wait around 48 hours before your first wash where possible, as this gives the colour time to settle. Use a sulphate-free, colour-safe shampoo and conditioner, and wash with lukewarm rather than hot water, which helps preserve tone and shine. Try to limit how often you wash, as frequent washing can fade colour more quickly. Heat styling and strong UV exposure can also dull the result, so use a heat protectant and consider a hat or UV-protective product in strong sun. A weekly nourishing mask helps maintain condition, particularly if your hair was already dry or previously lightened. Your stylist may recommend a toning or purple shampoo or an occasional gloss to keep the tone fresh between visits. If you swim, wet your hair with clean water and apply conditioner beforehand, as chlorine and salt water can affect coloured hair. Follow any specific product advice your stylist gives, as this is tailored to your hair.

Lowlights are generally a low-risk salon treatment, but because permanent and many semi-permanent colours contain dyes such as PPD that can trigger allergic reactions, safety centres on proper testing and a competent, insured stylist. An allergy alert test carried out ahead of your appointment is the key safeguard, and it matters even if you have been coloured many times before, because a sensitivity can build up over repeated exposure. Skipping this step is a real concern: if a reaction occurs and no test was done, an insured practitioner can be found at fault in a claim, and more importantly you risk an avoidable reaction. A skilled stylist will also protect your scalp, mix and apply products correctly, and monitor development time to avoid over-processing that can damage the hair. Tell your stylist about any scalp conditions, previous colour reactions, medications or recent treatments, as these can affect suitability. Reputable salons follow manufacturer guidance and keep records of your tests and colour history.

Lowlights are a cosmetic hair treatment rather than a medical procedure, but there are a few health points worth flagging to your stylist. The most important is allergy risk: hair colour ingredients, particularly PPD, can cause contact dermatitis or, rarely, more serious allergic reactions, so any history of reaction to hair dye, temporary black henna tattoos or related chemicals should be raised, and an allergy alert test carried out. If you have a scalp condition such as psoriasis, eczema or broken or irritated skin, or you are undergoing treatment that affects your skin or hair, mention this, as colouring may need to wait. Some people prefer to avoid or postpone chemical hair colour during pregnancy; current UK advice generally regards occasional use as low-risk, but if you have any concerns it is sensible to speak to your GP or midwife. If you have had a previous reaction or are unsure about your suitability, seek advice from your GP or a dermatologist before booking. Your stylist is not a medical professional and cannot diagnose or treat skin conditions.

Yes. An allergy alert test, sometimes called a patch or skin test, is strongly recommended before any colour containing dyes such as PPD, and reputable UK salons treat it as standard. It is usually done at least 48 hours beforehand by applying a small amount of product behind the ear or on the inner arm and watching for any reaction. It matters even if you have been coloured before, because sensitivities can develop over time with repeated exposure. Framed around risk and liability, skipping the test can leave an insured stylist found at fault if a client reacts, and it protects you from an avoidable reaction. It is worth knowing that a patch test is a helpful safeguard rather than a guarantee, as it cannot rule out every possible reaction, so any tingling, itching or swelling during colouring should always be reported straight away.

Be cautious if a salon offers to colour your hair with a permanent or dye-based product without ever mentioning or carrying out an allergy alert test, or dismisses your request for one because you have been coloured before. Other warning signs include a stylist who does not ask about your hair history, scalp condition, medication or previous reactions, or who rushes you into a service without a proper consultation. Reluctance to discuss the shades, likely condition of your hair after lightening or realistic maintenance is also a concern. Premises that look unclean, reuse products in an unhygienic way, or cannot confirm they are insured should give you pause. During the treatment, burning, stinging, significant itching or swelling of the scalp is not normal and should be raised immediately rather than left to develop.

Good practice starts with a thorough consultation where the stylist looks at your hair's condition and history, discusses the shades and placement, and sets honest expectations about the result and upkeep. They will arrange an allergy alert test ahead of your appointment when dye-based colour is being used, keep a record of it, and explain why it matters even for regular colour clients. A reputable stylist is qualified, insured and works in clean premises, mixes and applies products according to manufacturer guidance, and monitors development time to protect your hair. They will ask about scalp conditions, medications and past reactions, tailor the depth and contrast to suit you, and be willing to say when a look may not be achievable in one visit. Clear aftercare advice and a sensible maintenance plan are also signs of a considerate, professional service.

Will I need an allergy alert test, and when should it be done before my appointment?
Which shades and placement do you recommend for my natural colour and skin tone, and how much contrast will there be?
Will lowlights damage or dry out my hair, especially if it has been lightened before?
How long will the appointment take, and how many foils or sections are involved?
How often will I need to come back for maintenance, and what will that cost?
What aftercare and products do you recommend to keep the tone and condition looking good?

Having lowlights applied is generally comfortable and relaxing. You may feel the gentle tension of your hair being sectioned and, with foils, a slight weight or warmth as they sit close to the scalp while the colour develops. The colour itself should not sting or burn; a mild coolness or the sensation of product on the scalp is normal, but any noticeable itching, tingling, stinging or burning is not and should be mentioned to your stylist straight away, as it can signal a reaction. The rinsing, toning and conditioning stages are usually soothing, and the blow-dry at the end is comfortable. If you have a sensitive scalp, let your stylist know so they can take extra care with sectioning and product placement.

There is no downtime with lowlights, and you can return to your normal routine straight away. The main thing to be mindful of is giving the colour time to settle, so ideally delay washing for around 48 hours and avoid heavy heat styling in the first day or two. In the rare event you notice scalp itching, redness, swelling or discomfort after colouring, rinse the area and seek advice, as this can signal a reaction to the dye. Otherwise, coloured hair simply benefits from gentle, colour-safe care to keep the tone and shine looking fresh for as long as possible.

Lowlights typically last around six to eight weeks before regrowth and fading become noticeable, though this varies with how fast your hair grows, how often you wash it and the products you use. Because the darker tones are woven through rather than covering the whole head, regrowth tends to be softer and more forgiving than an all-over colour, which can make the look easier to maintain. To keep the result fresh, use colour-safe, sulphate-free products, wash less frequently and in lukewarm water, and protect your hair from strong heat and UV. A toner or gloss every few weeks helps maintain the tone and adds shine, and a regular conditioning mask keeps the hair in good condition, particularly if it has also been lightened. Your stylist can advise on the right interval between appointments for your hair and the effect you want, and the depth and contrast can be adjusted over time as your natural colour or preferences change.

Single Process Colour

Single process colour is a permanent or semi-permanent hair colour applied in one step, usually an all-over base colour worked from root to tip or a root regrowth touch-up. Unlike highlights or balayage, it produces an even, uniform tone rather than dimensional lightness. A colourist mixes a tint with a developer (peroxide) to open the hair's cuticle and deposit or lift colour, so it can cover grey, deepen or refresh your natural shade, or shift your tone warmer or cooler. The finished result can be tailored closely to you, from a subtle few-shades change to full grey coverage, and your colourist will factor in your natural level, any existing colour and your skin tone. Most permanent and many semi-permanent dyes contain PPD (paraphenylenediamine) or related chemicals, which give long-lasting colour but can trigger allergic reactions in some people, which is why an allergy alert test matters. It is one of the most popular salon services in the UK and, carried out by a trained colourist on healthy hair, typically gives reliable, even, long-lasting results. Regrowth usually shows within four to six weeks, so single process colour is generally maintained with regular appointments.

Service

Single Process Colour

The most important step is an allergy alert test at least 48 hours before your appointment, particularly if you are a new client, have changed brand or shade, or it has been more than six months since your last colour. Arrive with hair that has not been freshly washed on the day, as a little natural oil helps protect your scalp, but keep it free of heavy styling product. Tell your colourist about any recent home colour, henna or box dye, as these can react unpredictably with salon products. Avoid scratching, exfoliating or treating your scalp right beforehand. Bring photos of shades you like and be honest about your colour history, including any previous lightening. If you have a sensitive or broken scalp, a recent reaction, or you are pregnant or breastfeeding, mention it so your colourist can advise. A proper consultation lets them assess your hair's condition and agree a realistic, tailored result with you before any product goes on.

Your colourist will begin with a consultation, checking your hair and scalp, confirming your allergy alert test result and agreeing the shade. They will section your hair and apply the tint with a brush, either all over or just to the regrowth if you are maintaining an existing colour. You will usually feel a cool, slightly wet sensation as the product goes on; it should not sting or burn. The colour is then left to develop for a set time, typically around 20 to 45 minutes depending on the product and result wanted, sometimes with gentle heat. Once developed, your hair is rinsed thoroughly at the basin, often with a colour-safe shampoo and conditioner or a bond treatment. A tone or gloss may be added to refine the finish. Your colourist will then cut or blow-dry as booked. Tell them straight away if you feel any burning, intense itching or discomfort at any point, as this is not normal and needs attention.

To protect your investment, wait around 48 hours before your first wash where possible, as this gives the colour time to settle into the hair. Use a sulphate-free, colour-safe shampoo and conditioner and wash a little less often, as frequent washing fades colour faster. Lukewarm rather than hot water helps keep tone true and the cuticle smooth. A weekly mask or bond treatment supports condition, since colouring can leave hair drier. Heat styling is fine, but a heat protectant reduces damage and fade. UV, chlorine and salt water can shift colour, so a hat or UV-protective product helps on holiday, and rinse hair after swimming. Blondes and cool tones may need a purple or blue toning shampoo occasionally to counter brassiness. If you notice any delayed scalp itching, redness, swelling or a rash in the days after, contact your colourist and seek advice from a pharmacist or GP, as this can indicate an allergic reaction.

The single most important safeguard is a valid allergy alert test carried out at least 48 hours before colour, because permanent and many semi-permanent dyes contain PPD or related chemicals that can cause allergic contact dermatitis, and in rare cases a severe reaction. Choose a trained, insured colourist who follows the manufacturer's and their trade body's testing protocol and keeps clear records. Permanent colour should be applied to the scalp only with appropriate products and developer strengths, and lightening or high-lift work needs particular skill to avoid over-processing and breakage. A genuine reaction is not the same as mild, brief scalp tingling; burning, spreading itching, swelling or blistering are warning signs that mean the product should be removed and advice sought. Never let anyone skip your patch test to fit you in sooner. If you have ever reacted to hair dye or to a black henna temporary tattoo, tell your colourist, as this raises your risk and may mean colour is not safe for you.

Share your full health picture at consultation. If you have a history of allergic reactions to hair dye, eczema or psoriasis on the scalp, a broken or inflamed scalp, or a previous reaction to black henna temporary tattoos, colour may not be suitable and your colourist may decline or seek further advice. Allergies can develop at any point in life, even to a product used safely many times before, which is why testing before each colour cycle matters. Pregnancy and breastfeeding are common questions; current NHS information suggests the small amount of chemical absorbed is generally considered low risk, but many people choose to wait until after the first trimester or use gentler options, and you should check with your midwife or GP if unsure. Certain medicines and health conditions can affect the scalp or hair, so mention anything relevant. Hair colour is a cosmetic service, not a medical treatment; if you have significant scalp problems, sudden hair loss or a suspected allergy, see your GP or a pharmacist.

Yes. A skin allergy alert test (patch test) is standard and important for hair colour and should be done at least 48 hours before your appointment, ideally on the inner elbow or behind the ear, following your salon's and the manufacturer's protocol. It is needed for new clients, after any change of brand or shade, and typically if more than six months have passed, because allergies can build over time even to a product used safely before. Skipping it is a real liability risk: if a client reacts and no valid test was recorded, an insured colourist can be found at fault in a claim and cover may be affected. Importantly, a patch test reduces but does not eliminate risk and cannot guarantee no reaction, so it sits alongside an honest consultation and health check rather than replacing them.

Be cautious if a salon offers to skip or rush your allergy alert test, or applies colour the same day as a first-ever test without the 48-hour wait. Reluctance to discuss your colour or health history, or to explain what product and developer strength they are using, is a concern. During the service, burning, stinging, intense itching, swelling or blistering of the scalp are not normal and mean the product should be removed at once. A colourist who dismisses these sensations, cannot show insurance or training, keeps no client records, or pressures you into dramatic lightening on already damaged hair is a warning sign. Promising permanent colour will fully lift very dark or previously box-dyed hair in one session, with no honest talk of condition or breakage, is also a red flag.

A good colourist gives a proper consultation, checks your hair and scalp, and confirms a valid allergy alert test before mixing anything. They ask about your colour and health history, including home dye, henna and any past reactions, and keep clear written records with your sign-off. They explain the shade, the developer strength and realistic results, and set honest expectations about grey coverage, tone and how many sessions dramatic changes may need. Look for visible hygiene, current insurance and recognised training or qualifications, and willingness to protect hair condition with bond or conditioning treatments. They tailor the result to your natural level and skin tone rather than pushing a one-size-fits-all shade, take care around your hairline and scalp, and give you tailored aftercare advice at the end.

Will I need an allergy alert test, and can it be done at least 48 hours before my colour?
Are you trained and insured for colour work, and do you keep client record cards?
Given my natural colour and history, is the shade I want realistic in one session?
How will you protect my hair's condition, especially if any lightening is involved?
How often will I need to come back for regrowth, and roughly what will maintenance cost?
What should I do, and who do I contact, if I notice any reaction or irritation afterwards?

As the colour is applied you will usually feel a cool, slightly wet, tickly sensation on the scalp, and the product has a distinct smell. Some people notice very mild, brief warmth or tingling as it develops, which typically settles quickly and is not a cause for concern. What you should not feel is burning, stinging, strong itching or pain; these are not normal and you should tell your colourist immediately so the product can be removed. Rinsing at the basin feels cool and soothing. Afterwards the scalp usually feels completely normal, though it may be a touch sensitive for a short while. Any increasing itch, redness or swelling in the hours or days after is a warning sign, not a typical sensation.

There is no real downtime after single process colour and you can return to normal activities straight away. Your scalp may feel very slightly sensitive for a short time, which typically settles quickly. The main thing to be aware of is colour transfer in the first day or two, so avoid light-coloured pillowcases and take care with pale clothing until after your first wash. Colour can look a touch deeper or more intense at first and usually softens as it settles over the first few washes. If, rather than mild tightness, you develop increasing itching, redness, swelling or a rash on the scalp, hairline, ears or neck in the hours or days afterwards, treat this as a possible allergic reaction and seek advice promptly.

Results are immediate: an even, all-over tone with grey coverage or a refreshed, deepened or subtly changed shade, tailored to suit you. Permanent colour does not wash out, but it fades and softens over time, and regrowth typically shows at the roots within four to six weeks, which is when most people book a root touch-up. Semi-permanent and gloss versions fade more gently over several weeks. To keep colour looking its best, use sulphate-free colour-safe products, wash a little less often in lukewarm water, and use toning products where relevant to control brassiness in blondes and cool tones. Regular conditioning or bond treatments help maintain shine and condition between visits. How often you return depends on how fast your hair grows, how much grey you are covering and how much contrast there is between your natural and coloured shade. Your colourist can suggest a maintenance schedule and gloss or toner top-ups to stretch the time between full colours.

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.
