How long does a keratin treatment last?
Brands typically quote results in weeks to a few months, and the result fades gradually rather than ending on one day.
How long it holds for you varies with hair texture, how often you wash the hair and what you wash it with. The aftercare guide covers the habits that matter.
How long does a keratin Express treatment last?
Express versions are generally described as a lighter, shorter treatment, with a correspondingly shorter result than the full version.
The manufacturer's information for the exact product is the reference; ask the specialist which version applies to you.
How long does keratin last on wavy or curly hair?
Texture changes it: wavy and curly hair tends to show the return of its natural pattern earlier than straight hair.
Curly hair also needs more moisture and handling care, which affects how the result holds. See why keratin fades faster on curly or chemically treated hair.
How long does a smoothing sealant last through washes?
Brands tie the result to washing: each wash takes a little of the smoothing out, so the result fades gradually with the number of washes.
Gentle shampoo, less frequent washing and less heat slow it down.
How often should you get a keratin treatment?
How often depends on the condition of your hair and how quickly the smoothing fades, and the specialist decides at the consultation.
Repeat treatments usually focus on the new growth, and hair that is already stressed needs more time between visits. The consultation costs $0 and takes 20 min.
What does hair look like after a few months?
After a few months the smoothing has softened, hair is back to more of its natural texture and the roots show the new growth.
A gradual change is the treatment fading, not failing. Hair that turns dry, rough or starts to break is a different matter; tell your specialist.
Will my hair go back to normal after a keratin treatment?
Yes: the smoothing fades and your natural texture returns as the product washes out and the hair grows.
Curls come back gradually, not all at once, and there is no way to undo the treatment on demand. If you want to keep your curls, ask about hair botox instead.
How do I make a keratin treatment hold longer?
Wash less often, use gentle products made for smoothed hair and keep heat low.
The full list is in living with keratin.
What drives the price of a keratin treatment? Hair length and hair thickness set the price: at kruLA a keratin treatment runs from $220 for shoulder length and shorter to $550 for butt length and longer, and thick hair adds $30 to $50.
Thickness is measured before the treatment, and the session takes 2 h to 3 h 30 min depending on length. Every length step is on the prices page, and the keratin treatment page has the booking button.
Keratin timing FAQ
How long is keratin treatment?
The visit takes 2 h to 3 h 30 min at kruLA, from 2 h for shoulder length and shorter to 3 h 30 min for butt length and longer. Thick hair takes more time.
Is keratin hard to maintain?
No: maintenance is a few habits, not a routine of its own, and the main ones are gentle washing and low heat. Most people find it shortens the routine.
Can you get too many keratin treatments?
Too many can stress hair that is already fragile, so the specialist decides at the consultation ($0, 20 min) when another treatment makes sense. Repeat treatments usually focus on the new growth.
Is keratin shampoo bad for your hair?
A shampoo that suits smoothed hair is sulfate-free, and the specialist can tell you which to buy for the product used. Harsh shampoos are the thing to avoid.
Is too much keratin shampoo bad for hair?
Heavy shampoos or masks can weigh the hair down or leave build-up. Use what the specialist recommends and rinse well.
Is keratin shampoo good for thin hair?
It can be, in light amounts, since thin hair goes limp easily. Ask your specialist about root volume; BIO keratin ($220 to $550) is the kruLA smoothing described as keeping natural volume.
Can we use other keratin shampoo and conditioner after keratin treatment?
Ask your specialist first: the shampoo and conditioner should be made for smoothed hair, usually sulfate-free, and fit the product used. Follow the sheet your specialist gives you.
Can any other shampoo and conditioner be used after keratin treatments?
Not any: check the label for sulfates and heavy oils, and ask your specialist for products that suit the product used. Follow the sheet your specialist gives you.
