Keratin Treatment for Curly Hair: What to Expect
Keratin smooths frizz and loosens curls for months – but it is not the only choice for curly hair. Here is what really happens to your curls, how long it lasts, and when a Brazilian Blowout or protein suits them better.
Quick answer
A keratin treatment for curly hair smooths frizz and loosens your curls, so hair dries smoother and blow-dries straight in a fraction of the time. It lasts up to 6 months, takes 2 – 4 hours and costs AED 420 – 895 in Dubai. It is semi-permanent: as it washes out over the months, your natural curl gradually returns. Want to keep your curls and just lose the frizz? A Brazilian Blowout is usually the better match.
In Dubai’s humidity, curly hair is hard work: defined morning curls turn into frizz by lunchtime. That is why keratin for curly hair is one of the most common questions our specialists hear. The honest answer: keratin is excellent for curly hair, as long as you know what it will do to your curl pattern before you book.
Will keratin straighten curly hair?
Keratin is a smoothing treatment: the formula is applied section by section, blow-dried and sealed into the cuticle with a flat iron. Hair comes out smoother, glossier and much less frizzy, and curls are relaxed and loosened. How straight it looks depends on where you start:
- Wavy hair can be left smooth and straight, or with just a soft bend.
- Curly hair loosens noticeably, and a quick blow-dry gives a sleek, straight finish.
- Tight or very curly hair is softened and much easier to manage, but is relaxed rather than made poker-straight.
Does keratin ruin curls? Will my curls come back?
Keratin is semi-permanent. It lasts up to 6 months (usually 3 – 6) and then fades gradually as you wash your hair, so your curl slowly returns. New hair also grows from the roots with your natural texture. You can repeat keratin whenever you like, or let it wash out if you miss your curls.

Frizz and humidity
Keratin treatment for frizzy curly hair
Curly hair reacts quickly to humidity: volume you did not ask for and curls that lose their shape. Keratin fills gaps in the cuticle and smooths it flat, which means:
- Far less frizz, even on humid summer days
- Faster blow-drying – smooth hair in much less time
- More shine, because a smooth cuticle reflects light
- Results for months – up to 6 with good aftercare

Smooth or keep your curls?
Keratin vs Brazilian Blowout for curly hair
Both remove frizz and add shine. The real question for curly hair is how much of your curl you want to keep.
| Brazilian keratin treatment | Brazilian Blowout | |
|---|---|---|
| What it does to curls | Relaxes and loosens them for maximum smoothness | Smooths frizz while keeping natural volume and movement |
| Styling afterwards | Dries smoother and straighter; quick blow-dry | Wear it curly or straight – curls dry more defined and less frizzy |
| Appointment time | 2 – 4 hours | From 80 minutes |
| First wash | As your specialist advises – usually after 48 – 72 hours | Same day – wash, exercise or wear a ponytail straight away |
| How long it lasts | Up to 6 months | Up to 12 weeks (10 – 12 weeks with Brazilian Blowout aftercare) |
| Price from | AED 420 | AED 685 |
Choose keratin for maximum smoothness
Tired of fighting your curls every morning? Keratin gives the sleekest result and lasts the longest – up to 6 months – so most clients book it two or three times a year.
Brazilian Blowout for curly hair you want to keep
Love your curls and just want them calmer? A Brazilian Blowout keeps more natural movement and volume, and curls dry more defined and less frizzy. It is cumulative – the more often you have it, the healthier your hair will be.

Wavy hair
Keratin for wavy hair
Keratin works well on wavy hair: because the wave is already loose, it can leave hair smooth and straight with a glossy shine – ideal if you straighten your hair every day. If you like your waves, a Brazilian Blowout keeps that soft movement while removing the frizz. Tell your specialist which finish you want at the consultation.
Keratin for curly hair without straightening
Keratin always loosens curls to some degree. If your goal is frizz-free curls rather than straighter hair, we will usually suggest the Brazilian Blowout instead.
Protein for curls that are frizzy because they are weak
Not all frizz comes from humidity. Curls that have been coloured, bleached or heat-styled for years can become porous, dry and weak – rough, snapping when brushed and frizzy whatever the weather. They need strength as much as smoothing.
A protein hair treatment fills weak, porous areas of the hair and seals them in, so curls feel stronger, smoother and shinier. It takes 2 – 3 hours, lasts 3 – 5 months and starts from AED 475; a root protein touch-up (AED 330) later refreshes just the regrowth. If curls are breaking after heavy lightening, we may suggest an Olaplex treatment first. More in keratin vs protein treatment.
Your curl type
Which treatment for your curl type?
A starting point for your consultation. Your specialist will look at your hair’s thickness, condition and colour history before recommending a treatment.
| Curl type | If you want… | Treatment to consider | Good to know |
|---|---|---|---|
| Wavy hair | Smooth, close-to-straight hair – or soft waves without frizz | Keratin for a sleek finish; Brazilian Blowout to keep the wave | Keratin can leave wavy hair smooth and straight |
| Curly hair | Looser curls and a fast, straight blow-dry – or defined curls with less frizz | Keratin to loosen and smooth; Brazilian Blowout to keep your curls | Brazilian Blowout lets you wear it curly or straight |
| Tight curls | Softer, more manageable hair that is quicker to style | Keratin | Curls are relaxed rather than poker-straight; very curly hair may need a refresh sooner |
| Frizzy curls that feel weak or dry | Stronger, smoother, shinier curls | Protein treatment | Very fragile or bleached hair may need Olaplex first |

Thick and very curly hair
Keratin treatment for thick curly hair: time and price
Thick curly hair takes the longest, because every section is coated, blow-dried and sealed with a flat iron – plan for the full 2 – 4 hours of a keratin appointment. A Brazilian Blowout takes as little as 80 minutes, a little longer for very long or very thick hair.
Prices are set by hair length. Very thick hair may cost a little more because it needs extra product, and we always confirm your price before we begin. Send a photo of your hair from the back on WhatsApp for a quick quote.

Aftercare for curly hair after keratin
Very curly or porous hair may need a refresh sooner, so aftercare matters even more:
- Keep hair dry, loose and untied until your first wash – usually 48 – 72 hours, as your specialist advises.
- Use sulfate-free shampoo and conditioner – sulfates wash keratin out faster.
- Wash 2 – 3 times a week with lukewarm water.
- Blow-dry smooth on humid days and use a heat protectant before every blow-dry or flat iron.
- Avoid pools and the sea for at least the first week.
- Sleep on a silk or satin pillowcase.
After a Brazilian Blowout there is no waiting time, and Brazilian Blowout aftercare helps results last 10 – 12 weeks. See the full plan in our keratin aftercare guide, and keep curls soft with a monthly Signature Hair Spa.
What is the best treatment for curly frizzy hair?
It depends on the cause. For humidity frizz and the smoothest, longest result, choose keratin. To keep your curls and wash the same day, choose a Brazilian Blowout. For weak, dry or over-processed curls, start with protein. Planning a colour? Colour first, or wait about two weeks after smoothing.

Frequently asked questions
Will keratin straighten curly hair?
Keratin relaxes and loosens curls and removes frizz, so curly hair dries smoother and blow-dries straight much faster. How straight it looks depends on your natural curl: wavy hair often ends up close to straight, while tight curls are softened and loosened rather than turned poker-straight.
Will my curls come back after keratin?
Yes. Keratin is semi-permanent, not a permanent change. It lasts up to 6 months and fades gradually as you wash your hair, so your natural curl slowly returns. New hair also grows from the roots with your natural texture.
Can I get keratin for curly hair without straightening it?
Keratin always loosens curls to some degree, because smoothing is what it is designed to do. If you want to keep your curl pattern and simply lose the frizz, a Brazilian Blowout is usually the better match: curls dry more defined and less frizzy, and you can still blow them out straight.
Is a Brazilian Blowout good for curly hair?
Yes. A Brazilian Blowout smooths frizz while keeping natural volume and movement, so you can wear your hair curly or straight. It takes as little as 80 minutes, lasts up to 12 weeks and you can wash your hair the same day. Prices start from AED 685.
How much is a keratin treatment for curly hair in Dubai?
Keratin costs AED 420 for short hair, AED 575 for medium, AED 740 for long and AED 895 for very long hair, VAT included. Very thick hair may cost a little more because it needs extra product, and we always confirm your price before we begin.
How long does keratin take on thick curly hair?
A keratin appointment takes 2 to 4 hours. Very long or very thick curly hair sits at the longer end, because every section is coated and then sealed with a flat iron.
What is the best treatment for curly frizzy hair?
It depends on why your curls frizz and the finish you want.
