Most keratin treatments on the market use harsh chemicals that deliver results through damage rather than repair. Keratin Revolution is built around science-led formulation that works with the hair's natural structure rather than against it. Our treatment delivers genuine smoothness, shine, and strength — results that last — without compromising the integrity of the hair. We've also built a complete professional ecosystem around the treatment: a retail aftercare range, training and certification, and dedicated Pro support that most competitors simply don't offer.

No. Keratin Revolution is based on glyoxylic acid— and contains no added formaldehyde. We want to be completely matter of fact about this. Glyoxylic acid is a well-established active ingredient in professional keratin treatments and works by forming bonds within the hair's structure to deliver smoothness, shine, and manageability — without the health risks associated with formaldehyde-based products. It's safe for use in a professional salon environment, and your clients can feel confident about what's going into their hair.

Key Fact :-

Keratin Revolution is glyoxylic acid based with no added formaldehyde. When a client or colleague asks, you can answer that clearly and with confidence. Full safety data sheets are available on request from hello@keratinrevolutionpro.com.

Results typically last 8 to 12 weeks, depending on the client's hair type, lifestyle, and homecare routine. Clients who use the Keratin Revolution aftercare range — specifically the Smooth & Moisture shampoo and conditioner — consistently see results lasting toward the longer end of that range. This is also a great opportunity to drive retail sales: the aftercare products genuinely extend the life of the treatment, making them an easy and honest recommendation.

Yes — Keratin Revolution is safe for use on colour-treated, highlighted, and chemically processed hair. In fact, many clients find the treatment improves the condition and appearance of previously processed hair by adding smoothness and shine. As always, a thorough client consultation is essential before any chemical service, and we recommend following our Application Instructions for clients with heavily processed hair.

Our retail range is designed to work as a complete system alongside the treatment. Key products include:

• Smooth & Moisture Shampoo & Conditioner — SLS and SLES free, formulated specifically to maintain and enhance the results of all Keratin Revolution treatments
• Silk Coat — our blow-dry spray with anti-humidity and UV protection; the perfect in-salon retail product
• Formula.Five — our molecular repair mask, a direct alternative to K18 at a more accessible price point
• Argan Oil — finishing and nourishing treatment for added shine and smoothness
• One.Leave — our leave-in conditioner with UV and heat protection, launching mid-2025

Each product has been developed to retail naturally from the treatment conversation — making it easy for your team to recommend and sell without it ever feeling pushy.

Formula.Five is Keratin Revolution's advanced molecular repair treatment— our answer to K18 and similar bond-building treatments, at a more accessible price point for salons and their clients. It works at a molecular level to:

• Repair damaged hair — targeting breakage and weakness caused by chemical services, heat, and environmental damage
• Improve strength and elasticity — rebuilding the internal structure of the hair
• Increase softness and shine — delivering an immediate cosmetic improvement alongside the structural repair
• Protect against future damage — strengthening the hair before further chemical or heat services

Formula.Five is aleave-in treatment— it is not rinsed out. It can be used as a standalone treatment or alongside the keratin smoothing service for clients whose hair needs additional repair before or after the treatment.

Silk Coat is Keratin Revolution's lightweight blow-dry finishing spray— our answer to Colour Wow Dreamcoat. It is designed to:

• Reduce frizz and lock in smoothness post blow-dry
• Increase shine and enhance the finish of any style
• Protect against humidity — keeping the hair smooth and frizz-free in damp or humid conditions
• Protect against UV and heat damage

Silk Coat is suitable for use on hair extensions and works on all hair types. It's one of our strongest retail performers — clients who experience it during the smoothing service almost always want to take it home. We recommend incorporating it into your service protocol as a standard finishing step.

The Detox Shampoo is a clarifying shampoo designed to remove build-up, refresh the scalp, and deeply cleanse the hair. It is particularly useful:

• As the first step of the keratin treatment protocol — clarifying the hair before treatment ensures the best possible penetration and result
• For clients who use styling products regularly and experience build-up between washes
• To resolve post-treatment stickiness caused by residual product

We recommend clients use the Detox Shampoo once or twice per week as part of their regular routine, alternating with the Smooth & Moisture Shampoo. It should not be used as an everyday shampoo as it is more stripping than the maintenance range.

Yes — Keratin Revolution does not test on animals. All products are cruelty-free. Our formulations comply with UK and EU cosmetic regulations, which prohibit animal testing on cosmetic products and their ingredients.

Yes — all Keratin Revolution products are fully compatible with each other and have been developed to work as an integrated system. You can layer and combine products to create customised results for your clients, which is one of the things that sets our range apart from single-product competitors.Here are some of the key ways to combine products in practice:

• Keratin Treatment + Nutritional & Repair Mask — blended for customisable results. You can mix the keratin smoothing treatment with the Nutritional & Repair Mask in different ratios to tailor the outcome for each client. A higher ratio of mask softens the smoothing effect and adds intense conditioning — ideal for clients who want more movement and less straightening. A higher ratio of treatment delivers maximum smoothness and frizz control. This gives you the flexibility to personalise the service rather than offering a one-size-fits-all result.
• Argan Oil + Silk Coat as part of the smoothing service protocol. Both the Argan Oil and Silk Coat can be incorporated into your smoothing service as finishing steps, adding shine, humidity protection, and a polished result that clients will notice immediately. They also make a natural retail recommendation at the end of the appointment.

Yes — and for clients with particularly damaged or compromised hair, we actively recommend it. Using the Nutritional & Repair Mask as a pre-treatment prep step helps restore some structure and strength to the hair before the keratin treatment is applied, which can improve both the application experience and the final result.The pre-treatment prep protocol is straightforward:

• Apply the Clarifying Shampoo and rinse thoroughly
• Apply the Nutritional & Repair Mask and leave for 4 minutes
• Rinse the mask out completely
• Proceed with the keratin smoothing treatment as per the standard application process

This additional step is particularly recommended for clients with heavily colour-treated, bleached, or heat-damaged hair. It takes only a few minutes and makes a noticeable difference to both the application and the longevity of the result.

Pro Tip :-

The pre-treatment mask prep protocol is also a great opportunity to retail the Nutritional & Repair Mask to the client for home use between treatments — position it as the product that keeps their hair in the best possible condition to maintain their results.

Yes — Keratin Revolution works on all hair textures, from bleach blonde over-processed hair all the way through to Afro and 4C textures. The product itself is effective across the full spectrum. What changes is not whether it works, but how it is applied — the application procedure varies depending on the hair texture, condition, and the result the client is looking for.Full in-depth guidance on working with different hair textures is covered in our training courses. As a general guide:

• Fine, bleach blonde, or over-processed hair — we recommend mixing the keratin smoothing treatment with the Nutritional & Repair Mask on a 50/50 ratio, creating more of a hair tox treatment. This is gentler on compromised hair and delivers a more natural, voluminous result.
• Thicker, coarser, or Afro textures — the full strength treatment is appropriate, and application technique will be adapted to ensure full coverage and penetration. Full guidance is provided in training.

Mixing the two products allows you to customise the treatment to match your client's hair texture, condition, and desired result — rather than applying a one-size-fits-all service.Take a client with fine, bleach blonde, over-processed hair as an example. They want to remove frizz — but because their hair is finer, a full-strength treatment could leave it looking flat and without volume. By mixing the keratin smoothing treatment with the Nutritional & Repair Mask on a 50/50 ratio, you dilute the smoothing effect while adding intense conditioning. The result is frizz reduction with maintained natural volume — a more flattering and natural-looking outcome for that hair type.Mixing also gives you a way to have a more nuanced client consultation — you can explain that you're tailoring the treatment specifically for their hair, which elevates the perception of the service.

Key Principle :-

The 50/50 mix is not a compromise — it's a customised treatment. For finer or over-processed hair, it delivers a more appropriate, more natural-looking result than full-strength treatment.

Yes — and intentionally so. With the 50/50 mix, the smoothing effect will not be as strong as with the full-strength treatment. However, the hair will maintain more of its natural volume and movement, giving a softer, more natural-looking result overall.For clients with finer hair who are concerned about their hair going flat, this is actually the more desirable outcome. It's about matching the result to what the client genuinely wants — and for many clients on finer hair, a lighter smoothing effect with preserved volume is exactly that.In terms of longevity, the 50/50 mix will typically last around two months, compared to three months or more with the full-strength treatment. This is worth communicating clearly to the client at consultation so they have accurate expectations.

That depends on your own pricing strategy — but there are a couple of factors worth considering. The cost of product is lower with the 50/50 mix, because you're replacing a portion of the keratin smoothing treatment with the Nutritional & Repair Mask, which sits at a lower price point. Your product cost per service is therefore reduced.Whether you pass that saving on to the client, absorb it as additional margin, or maintain a single treatment price across all hair types is a business decision for you. Many salons operate a single service price for simplicity — others build a tiered structure based on hair type and product used. Our pricing calculator spreadsheet can help you model both approaches accurately based on your actual product costs. Contact hello@keratinrevolutionpro.com to request a copy.

No — and this is an important distinction to make clearly with every client before the service. Keratin Revolution is a smoothing treatment, not a straightening treatment. It will not eradicate curl or make the hair poker straight.What it will do is significantly reduce frizz, smooth the hair, soften the curl, and make the hair far more manageable. Clients will find their blow dry time is greatly reduced, their hair is easier to style, and the results of their blow out last much longer. On curly hair, the treatment will soften and loosen the curl pattern — but the curl will still be there.Setting the right expectation at consultation is essential. A client expecting poker-straight hair will be disappointed. A client who understands they're getting smoother, more manageable hair with reduced frizz and a softer curl will be delighted.

Key Distinction :-

Smoothing, not straightening. Reduced frizz, softer curl, more manageable hair, faster blow dry — not poker-straight results. Set this expectation clearly at every consultation.

The treatment is not permanent, which is reassuring for any client who is trying keratin smoothing for the first time. It will not be locked into the hair forever. However, it is also not instantly reversible — it cannot simply be washed out or removed in a single session.The treatment fades progressively over time with each wash, typically over a period of around three months. So a client who is unhappy with their result will see their natural texture gradually return over that period as they wash their hair as normal. There is no specific removal process required — time and washing will do it naturally.This is another reason why the pre-service consultation is so important — ensuring the client understands and is happy with the expected outcome before the treatment is applied.

The Keratin Revolution smoothing treatment typically lasts three months or more. However, longevity is directly influenced by a number of factors that are worth discussing with your client at consultation:

• Aftercare products. The single biggest factor in longevity is the shampoo your client uses at home. We recommend the Keratin Revolution Smooth & Moisture Shampoo, which is SLS and SLES free and specifically formulated to maintain and extend the results of the treatment. Using a standard shampoo containing sulphates will significantly reduce how long the results last.
• Wash frequency. The more frequently a client washes their hair, the quicker the treatment will fade. Clients who wash less frequently will typically see results lasting toward and beyond the three-month mark.
• Swimming. Chlorinated pool water can affect the treatment and overall hair condition. Clients who swim regularly should be made aware of this.
• Sweating. Clients who exercise frequently and sweat heavily may find the treatment fades slightly faster. That said — see below — washing after exercise is absolutely fine.

Yes — there is no restriction on swimming after the treatment. However, as general haircare advice, chlorine is damaging to hair regardless of whether a client has had a keratin treatment or not. Repeated exposure to chlorinated pool water will affect the condition of the hair and can reduce the longevity of the treatment results.If a client's priority is to maintain their hair in the best possible condition and get the maximum life out of their treatment, we would advise against regular swimming in chlorinated pools. Where swimming is unavoidable, recommend rinsing the hair thoroughly with clean water immediately after leaving the pool, and using the Keratin Revolution aftercare range to help maintain condition.

Absolutely — gym and exercise are completely fine after the treatment, with no restrictions. One of the genuine advantages of the Keratin Revolution smoothing treatment is that there is no waiting period before the first wash — so a client can sweat during exercise and wash their hair the same day or the day after their treatment without any issue.This is a significant selling point worth highlighting to active clients, many of whom have been put off keratin treatments in the past by the restrictions associated with older formulas.

There is no waiting period before the first wash. Unlike many traditional keratin treatments that require clients to avoid washing for 48–72 hours post-service, Keratin Revolution has no such restriction. In theory, a client could wash their hair on the same day as the treatment, or the day after — whichever suits them.This offers clients much greater flexibility and removes one of the most common objections to keratin treatments — the inconvenience of the post-treatment waiting period. It's a strong point to lead with in your client consultations and marketing.

Key Selling Point :-

No waiting period before first wash. Clients can wash their hair the same day or next day post-treatment — no restrictions on exercise, sweating, or daily life. A significant advantage over traditional keratin treatments.

Yes — for the best possible results, we recommend that clients keep their hair down and loose until their first wash. That means avoiding hair ties, clips, grips, tucking the hair behind the ears, or anything else that could create a kink, crease, or mark in the hair while it is still in its setting phase.The practical implication of this is entirely in the client's control. Because there is no mandatory waiting period before the first wash, a client who washes their hair the same evening effectively has almost no restriction at all. A client who prefers to leave it longer before washing should keep it down in the meantime to protect the result.This is worth covering clearly at the end of every appointment as part of your post-service consultation — give the client a clear, simple instruction:"Keep it down and loose until your first wash — after that, style it however you like."

Post-Service Advice : Keep hair down and loose until first wash.No clips, ties, or tucking behind the ears. Since clients can wash whenever they like — even the same day — this is a minimal and easy instruction to follow.

We recommend between two and seven passes per section, depending on the hair texture. Unlike some other brands, the Keratin Revolution process is specifically designed to minimise the amount of heat required to achieve the desired result — protecting the health and integrity of the hair throughout the service.

• Fine, bleach blonde, or over-processed hair — two passes per 1cm section at approximately 180°C. Less heat, fewer passes — the hair is already in a more vulnerable condition and doesn't need or benefit from excessive heat.
• 4C, coarser, or more resistant textures — up to seven passes per 1cm section at 210°C to 220°C. The higher number of passes ensures the treatment penetrates and sets effectively on denser, more resistant hair.

Full guidance on sectioning, pass technique, and timing for different hair types is covered in depth during the Keratin Specialist Club training.

The treatment is applied to dry hair. After cleansing with the Clarifying Shampoo, the hair must be blow dried to 100% dry before the treatment is applied. This is an important step — applying to fully dry hair ensures even, complete coverage across the entire head, making it far easier to control the application and ensure no areas are missed.This is also one of the key reasons why ensuring the hair is completely dry before the flat iron stage is so important — see the question on post-treatment odour for more detail on why residual moisture at the flat iron stage can affect the result.

Yes — Keratin Revolution is fully compatible with colour, bleach, and all other chemical services, including relaxers. However, we strongly recommend allowing a period of one to two weeks between a colour or bleach service and the keratin treatment. Having multiple chemical services in quick succession is not good for the condition of the hair, and giving it time to settle between services delivers a better overall result and a healthier client experience.As a general principle — even when services are technically compatible — spacing them out is always better for the integrity of the hair. Build this guidance into your client consultation process and it will set you apart as a professional who genuinely prioritises hair health.

Yes — colouring after the treatment is fine, but timing matters. As a general guide:

• Wait a minimum of 7 days after the treatment before colouring
• Ideally allow 10 to 14 days if possible, to give the treatment time to fully settle into the hair
• Root touch-ups can typically be carried out sooner if required, as the product application is more targeted and less likely to affect the treated lengths

The same principle applies in reverse — if a client is having both a colour service and a keratin treatment, space them out to protect the condition of the hair. See the question on colour compatibility above for guidance on the recommended gap before the treatment.

This requires caution. Henna is a natural dye that can behave unpredictably when combined with professional treatments, and the outcome varies significantly depending on the type and formulation of henna used — natural henna behaves differently to compound henna or henna-based dyes that contain metallic salts. A strand test is essential before proceeding on any henna-treated hair. Do not skip this step. Carry out the strand test in an inconspicuous section and assess the result before committing to a full application. Results may vary and the strand test is the only reliable way to determine compatibility for that specific client's hair.

Important :-

Always perform a strand test on henna-treated hair before applying the treatment. Do not proceed without one. Results vary significantly depending on the henna used.

The correct flat iron temperature depends on the hair texture you're working with. Importantly, Keratin Revolution is effective at lower temperatures — and keeping temperatures lower is always better for the long-term health of the hair. As a guide:

• Fine, bleach blonde, or over-processed hair — work at approximately 180°C. Lower temperatures protect already compromised hair while still delivering effective results.
• Afro Caribbean and coarser textures — work at 210°C to 220°C. The higher temperature is needed to penetrate the hair structure effectively on denser, coarser hair.

Full guidance on flat iron technique for different hair textures is covered in depth in the Keratin Specialist Club training.

Key Principle : KR is effective at lower temperatures. 180°C for fine/bleached hair · 210–220°C for coarser textures. Lower is always better for hair health — never exceed what the texture requires.

The keratin smoothing service typically takes between two and three hours from start to finish. The exact duration depends on the texture, length, and density of your client's hair — coarser, thicker, or longer hair will naturally take longer to section, apply, dry, and flat iron thoroughly.When booking clients in, we recommend allowing three hours as a safe default to avoid feeling rushed, particularly for new clients whose hair you haven't worked with before. As you become more familiar with the process, you'll develop a better feel for timing different hair types.

While this is rare, it can occasionally happen — and it's important to handle it professionally. Always invite the client back in for a free consultation so you can assess the results for yourself in person before drawing any conclusions.It's worth noting that clients don't always have the most objective view of their own results. A client may feel there's been no difference when there genuinely has been — particularly if they were expecting a more dramatic outcome than the treatment delivers on their specific hair type. Your professional eye is important here. Seeing the hair in person, comparing it to your recollection of the pre-treatment condition, and giving your honest professional opinion is the right approach.If, after your assessment, you agree the result is genuinely unsatisfactory, contact the Keratin Revolution Pro team at hello@keratinrevolutionpro.com and we will work through it with you.

Yes — the keratin smoothing service is absolutely suitable for men , particularly those with longer hair or textured hair that they struggle to manage. There is a growing male client base for keratin treatments, and if you search social media you'll find a wealth of positive examples and before-and-after results from male clients who've had the service.The consultation, application process, and aftercare advice are the same as for female clients. The key factor — as always — is hair texture and condition rather than gender. If a male client has the right hair type and the right expectations, the service works just as effectively.

Yes — Keratin Revolution can be used on extensions, provided they are natural hair extensions. The treatment works on the natural hair structure, so synthetic extensions are not compatible. Natural hair extensions — whether bonded, tape-in, weft, or micro ring — can be treated effectively.We have many extension specialists in our Pro network using the Keratin Revolution system with excellent results, including our UK brand ambassador Kerry-Ann Buckell , who is a hair extension specialist and a strong advocate for the treatment on extension clients.

There is nothing to be concerned about. Once the keratin smoothing treatment has been applied and completed, the process is finished — there is nothing ongoing being absorbed or active in the hair. The treatment is set into the hair structure during the service itself.Our caution around pregnancy relates specifically to the application process — the product contact, the heat, and the salon environment during the service. A client who becomes pregnant after having a treatment has no cause for concern about the treatment they've already received.The practical implication is straightforward: if a client is pregnant and their treatment results begin to fade, they should wait until after their pregnancy before having the service repeated. As always, we recommend they consult their doctor or midwife if they have any concerns.

Reassurance :-

A client who becomes pregnant after treatment hasnothing to worry about— the treatment is complete once applied. The pregnancy caution applies to having anewtreatment during pregnancy, not to a treatment already received.
