How Long Does Keratin Treatment Last?
Up to six months – usually three to six, depending on your hair and how you wash it. Here is what to expect month by month, how long the appointment takes and when to book again.
Quick answer
A Brazilian keratin treatment lasts up to 6 months – usually 3 – 6 months, depending on your hair type, how often you wash it and whether you use sulfate-free aftercare. The appointment takes 2 – 4 hours, and the first wash is usually after 48 – 72 hours. Most clients repeat it two or three times a year.
“How long will it last?” is the first thing most women ask before they book a keratin treatment – and fair enough, because it decides whether the price and the hours in the chair are worth it. The honest answer is a range, not a single number. Two women can leave the same appointment with the same sleek hair and come back months apart.
This guide explains why, what your hair looks like at three and six months, how long the treatment itself takes, how often you can repeat it, and how the Brazilian Blowout and protein treatments compare.
How long does keratin treatment last?
Keratin is semi-permanent. It smooths the cuticle and coats each strand, and that coating softens a little every time you wash. So instead of switching off on a set date, the result fades gradually: frizz control and straightness ease off slowly until your natural texture is back.
On our menu the result is listed as up to 6 months. In practice most clients enjoy smooth hair for three to six months. At the same time, your hair keeps growing, and the new hair at the roots comes in with its natural texture – keratin only smooths the hair that was treated.
How long does keratin last on hair? Why it varies
Where you land in that 3 – 6 month range comes down to four things:
- How often you wash. Every wash softens the treatment a little, so washing daily uses it up faster than washing two or three times a week.
- Your shampoo. Sulfates are strong cleansers that strip keratin much faster than gentle sulfate-free formulas.
- Water, salt and chlorine. Regular swimming in the pool or sea, and very hot showers, shorten the result.
- Your hair type. Very curly or porous hair may need a refresh sooner than wavy or frizzy hair.
The first few days matter too – that is when the treatment sets. Our keratin aftercare guide covers the first week, washing, swimming and the products to use, so we won’t repeat it here.
Month by month
Keratin after 3 months and after 6 months: what to expect
Because keratin fades gradually, it helps to know what is normal at each stage – so you can tell the difference between a treatment that is simply wearing off and one that did not take.
The first 2 – 3 days
Hair is at its sleekest but the treatment is still setting. Keep it dry and loose until your specialist says you can wash – usually after 48 – 72 hours.
The first weeks
This is the full result: frizz-free in humidity, glossy, and quick to blow-dry. Many clients put the straightener away completely.
Keratin after 3 months
Most hair is still noticeably smoother than before. If you wash often or have very curly hair, you may feel frizz creeping back, and new growth at the roots has its natural texture.
Between 3 and 6 months
The smoothing softens wash by wash. Blow-drying starts to take a little longer again, and the difference between roots and lengths becomes easier to see.
Keratin after 6 months
For most clients the treatment has largely washed out and natural texture is back. If you loved the result, this is the natural time to rebook.
Regrowth
Keratin after 3 months: roots or a full treatment?
Sometimes the lengths still feel smooth at the three-month mark but the roots have grown out with their natural frizz or wave. You do not always need to repeat the full treatment straight away.
A root protein treatment smooths just the new regrowth at the roots, takes 1 – 1.5 hours and costs AED 330. It keeps you going until your next full treatment.
If the lengths have also lost their smoothness, a full keratin treatment is usually the better choice. Your specialist can look at your hair – or a photo on WhatsApp – and tell you which makes sense.
In the chair
How long does keratin treatment take in the salon?
Plan for 2 – 4 hours. The time depends mainly on your hair: short or fine hair is quicker, while very long or very thick hair takes longer, because every section is coated and then sealed with a professional flat iron.
- Consultation – your hair type, length, colour history and the finish you want.
- Clarifying wash – opens the cuticle so the keratin bonds evenly.
- Application – section by section, keeping a safe distance from the scalp.
- Blow-dry and seal – done in fine sections to lock the keratin into every strand.
- Aftercare plan – when to wash and what to use at home.
Plan for the days after, not just the appointment
The real time commitment is the appointment plus the no-wash period of usually 48 – 72 hours, when you also keep your hair loose and untied. So don’t book keratin the day before an event where you want an updo, or before a beach weekend. If you cannot avoid washing for that long, the Brazilian Blowout takes as little as 80 minutes and you can wash, exercise or wear a ponytail the same day.
How often can you get keratin?
Because keratin is semi-permanent and fades gradually, you can repeat it whenever the result has faded and you are ready – there is no fixed calendar. Most of our clients in Dubai book it two or three times a year, which fits the 3 – 6 month range.
Rather than rebooking on a set date, we suggest going by your hair. Before every repeat your specialist checks its condition. If it feels dry, weak or is breaking at the ends, smoothing again is not the first step: an Olaplex treatment or a protein treatment to repair and strengthen it may come first. Hair that is extremely damaged or heavily bleached may not cope well with the heat of the flat iron until it has been repaired.
Time to rebook?
Signs your keratin is wearing off
- Frizz comes back on humid days, even after a blow-dry
- Blow-drying takes noticeably longer than it did in the first weeks
- Your roots have grown out with your natural wave, curl or frizz
- Hair looks less glossy and feels less smooth through the lengths
- You are reaching for the straightener again most mornings
One or two of these at three months may only call for a root touch-up. All of them together usually means it is time for a full treatment.

How long do Brazilian Blowout and protein treatments last?
If longevity is your main question, here is how our smoothing treatments compare on how long they last, how long they take and when you can wash.
| Keratin treatment | Brazilian Blowout | Protein treatment | |
|---|---|---|---|
| How long it lasts | Up to 6 months (usually 3 – 6) | Up to 12 weeks (10 – 12 with Brazilian Blowout aftercare) | 3 – 5 months |
| Appointment time | 2 – 4 hours | From 80 minutes | 2 – 3 hours |
| First wash | Usually after 48 – 72 hours | Same day | As your specialist advises |
| With repeat treatments | Repeat when it fades | Cumulative – hair gets healthier each time | Root protein touch-up for regrowth |
| Price in Dubai | AED 420 – AED 895 | from AED 685 – AED 1,550 | from AED 475 – AED 950 |
Keratin gives the longest result of the three. The Brazilian Blowout lasts a shorter time but has no downtime, and because it is cumulative, the more often you have it, the healthier your hair will be. Rebook it when frizz returns, usually after 10 – 12 weeks. A protein treatment sits in between and focuses on strength as well as smoothing. Two non-smoothing treatments work differently: Olaplex results build up with each session, and the Signature Hair Spa is best repeated monthly.

Frequently asked questions
How long does keratin last on hair?
A keratin treatment lasts up to 6 months, usually 3 to 6 months. It fades gradually as you wash your hair, so the smoothness softens over time rather than disappearing overnight.
How long does a keratin treatment take?
Plan for 2 to 4 hours in the chair. Short or fine hair is quicker; very long or very thick hair takes longer because every section is coated and then sealed with a flat iron.
How often can you get keratin?
Keratin is semi-permanent, so you can repeat it when the result has faded and you are ready. Most of our clients book it two or three times a year, and your specialist checks the condition of your hair before every repeat.
Can I get keratin every 3 months?
Yes, if it has faded. Keratin lasts 3 to 6 months, so if you wash often or have very curly hair it may have softened by around 3 months, and you can repeat it then. If only the new growth at the roots is frizzy, a root protein touch-up for AED 330 can smooth the roots until your next full treatment.
Is keratin treatment permanent?
No. Keratin is semi-permanent: it smooths and straightens for up to 6 months, then fades gradually as you wash. New hair also grows in with your natural texture. It does not change your hair permanently the way rebonding does.
Why did my keratin not last long?
The usual reasons are frequent washing, shampoos with sulfates, chlorine or salt water, and very curly or porous hair, which may need a refresh sooner. Our keratin aftercare guide explains the routine that helps it last.
How long does a Brazilian Blowout last compared with keratin?
A Brazilian Blowout lasts up to 12 weeks – 10 to 12 weeks with Brazilian Blowout aftercare – while keratin lasts up to 6 months. The Brazilian Blowout is quicker, from 80 minutes, and you can wash your hair the same day.
How long does a protein hair treatment last?
A protein treatment lasts 3 to 5 months and takes 2 to 3 hours. When new growth appears, a root protein touch-up can smooth just the roots instead of repeating the full treatment.
