What happens if you wash keratin treatment before 72 hours? Does it ruin the treatment?

for washing it too early

  • Whenever you apply a keratin treatment on your hair, it is best not to wash your hair for at least 72 hours afterward.
  • If you wash it before that time, and you applied the keratin treatment to straighten the hair, it will lose its straightening effect.
  • If you apply the treatment to nourish and reduce frizz, your hair will become porous and frizzy again.
  • In other words, if you don’t respect these 72 hours, your hair will look the same as it did before you applied the keratin, and you’ll feel it duller and coarser, ruining the effects of the treatment.

Keratin is a protein found naturally in the hair fiber and is responsible for your hair being resistant, shiny, and growing every day.

When you apply dyes, use heat styling tools and/or bleach your hair, the hair fiber loses moisture and, consequently, loses keratin. That’s why keratin treatments are actually deep repairers of the hair fiber.


By doing this type of treatment on your hair, your cuticles will be sealed and hydrated. Some keratin treatments are straightening.

However, they all have one thing in common: you shouldn’t wash your hair for 72 hours after applying them.


 If you wash your hair before that time, the keratin treatment will lose its effect, no matter if you were looking for straighter hair or a more hydrated hair fiber with less frizz. 

Your hair will sadly be the same again.


  • If your hair was frizzy, and you wash it before 72 hours, the frizz will come back. You should not blame the stylist for your frizz. After all, you didn’t respect her directions.
  • If you had curls and applied keratin to straighten your hair, the curls will come back happier than ever. You should not blame the kit you bought online either.


  To achieve the results you are looking for, it is important to respect the application technique, exposure times, and fundamental care of the first 72 hours after applying keratin. 

If you don’t comply with this, there is no point in crying and kicking. Your hair will be the same again as if you had never applied keratin.

Can anything happen to your hair if you wash it before 72 hours?


No, your hair won’t fall out, you won’t start getting dandruff and you won’t have any allergic reactions. But the keratin will disappear.

In my salon, I always recommend that my clients don’t wash their hair for at least 72 hours after getting a keratin treatment.

Why it is important to wait 72 hours to wash your hair after a keratin treatment

shiny and silky

Perhaps the most important reason for not washing your hair for 72 hours is to avoid tears and disappointment.

After all, what was your idea to apply keratin to your hair?


I guess you wanted to achieve something.

It could be to reduce frizz, make your hair healthier, or even nourish your hair.

And it doesn’t matter if you apply it at home or in a salon. The aftercare will always be up to you.


Keratin is applied to the hair and, then, it is sealed with heat from a hairdryer. But it doesn’t end there.

It takes about 24-72 hours for the hair to fully absorb the keratin.

What happens if you wash your hair first?


 You’ll be removing the keratin, and the hair core won’t even know you were in the salon for three hours to do the treatment. 


If you don’t want to ruin the treatment, listen to me.

Don’t wash your hair before 72 hours. If you do, you won’t gain anything, but you’ll lose everything you were looking for when you decided to apply keratin to your hair.

Now, what happens after 72 hours?

That’s what I’m talking about next.


How to extend the keratin treatment longer

washing keratin treated hair

Once those first 72 crucial hours are over, you can wash your hair. Do you realize that everything comes, my little impatient one?

You can choose between two options. Also, to wash your hair, you must choose a shampoo with some special features.


Shampoo for keratin-treated hair.


Any of these options will leave your hair soft, shiny, and nourished, without affecting the keratin treatment.


Ph-balanced shampoo and without sodium.


These three shampoos will leave your hair free of residues, balancing the pH of your scalp and without generating oil or drying out.


Did you know that all keratin treatments are reactivated by heat?

That's why it's important that, after washing your hair, you dry it with a hairdryer, so that the heat reactivates the keratin and your hair keeps the docility and softness longer.


Protect your hair from the sun’s rays, because the direct sun on your scalp will make keratin disappear through perspiration.


  • Don’t wash your hair every day.

If you do, in four or five weeks there will be no trace of keratin left in your hair. Remember that keratin forms a protective film that is sealed with heat, and water "loosens" that film, until it is completely removed by washing.

The ideal situation is to wash your hair every 48 or 72 hours. This way, the hair fiber will keep its natural hydration and the one provided by the keratin you applied.



You should always wait 72 hours to wash your hair after applying a keratin treatment.

Otherwise, the treatment will lose its effect and you will have to repeat it to achieve the goals you wanted, whether it's straight hair or frizz-free hair.

And now, my little impatient girl, will you wait those 72 hours to wash your hair, or will you risk your hair being the same again?
