I had the keratin treatment, and I didn’t like it. How to get my hair back?

dry, frizzy, and burned hair

  • Your hair can’t go back to the way it was before applying the keratin treatment.
  • It’s because a keratin treatment is permanent.
  • What you can do is to soften its effects by avoiding reactivating the keratin with heat tools. Also, avoid washing your hair with shampoos and conditioners with keratin.

Unfortunately, if you want to get your hair back after keratin, you’ll have to be patient.

The keratin treatment lasts approximately three to six months according to your hair care routine.


 If you start washing your hair every day with shampoos and conditioners with sulfates, the keratin will fade faster. 

However, your hair health will also fade faster. I don’t think that’s what you’re looking for.


When you apply a keratin treatment, you modify the hair structure permanently.  

The keratin will disappear when the protein wears out. Then, your hair will go back to the way it was before the application.

So, what can you do?


As the old saying goes: if you can’t beat the enemy, join him!

What do I mean?

heat activates keratin

You’ll need to avoid some actions that deepen the effects of the treatment.


  • Keratin is activated by heat. So, forget about blow-drying and flat ironing your hair for a while.

The keratin won’t disappear. At least, you won’t activate it with heat. Also, if you hated that perfect straight effect, avoiding the flat iron will help.

For the first two weeks after application, your hair will look straight, frizz-free, and volatile.

Don’t worry. That keratin effect lasts for a short time. To be exact, it lasts for a maximum of two weeks.

If you don’t use a blow dryer or flat iron, you’ll notice that some waves begin to appear in your hair. At first, they’re almost imperceptible, but they are there.

You can braid your hair before going to bed to help the waves return.


  • Don’t use shampoo and conditioners with keratin.

You should avoid the “wet in the rain” effect.  It means that you should avoid depositing more keratin in your hair. 


It’s because your hair absorbs everything you apply to it.

One of the tips from stylists after applying keratin is to use shampoos and conditioners with keratin. Those shampoos extend the effects of the treatment.

At this time, you want exactly the opposite.  So, use shampoos and conditioners without keratin or sulfates. 

What’s more, if possible, use dry shampoo.



Many women complain that their hair gets greasy after keratin, and that’s why they want to get rid of the treatment.

As their hair is too greasy, they wash it every day.  However, this is not necessary because the hair isn’t dirty.


What actually happens is that the keratin treatment seals the cuticles and restructures the hair to repair the damage.

In the meantime, nature takes its course, and the scalp releases natural oils that deeply moisturize your hair.

As your hair is healthy and the cuticles are sealed by the keratin treatment, the hair fiber doesn’t hold the natural oils.

Then, the greasiness increases.


If that’s your case, use dry shampoo instead of washing your hair

Dry shampoo is sprayed 10 centimeters from the roots. Then, massage the scalp for two or three minutes, and remove excess shampoo with a brush or comb.


  • If you have to renew your hair dye right after the treatment, don’t wait for a day longer.

Permanent hair dye opens the hair cuticles. Then, some of the keratin will be removed.

These are all things you can do to disguise the effects of keratin on your hair.

However, to get your hair back to how it was before you applied keratin, you’ll need to wait for at least three months.

In the meantime, you’ll notice some subtle changes. And that’s what I’ll talk about next.


What will my hair look like as the keratin wears off?

Day 1 to day 15 after keratin application

These days will be hell for you. Your hair will look completely straight. If that’s not what you were looking for, it may even look lifeless and dull.

Remember,  if you don’t use the flat iron, you don’t reactivate the keratin. 


Day 15 to day 30

The straight effect is less noticeable every day. Some waves may appear in your mane.  You’ll also start to notice that you have more frizz. 

This is because you stopped activating the keratin, and you’re probably not using shampoos and conditioner with keratin.


Day 30 to day 70

At this stage, you’ll start to see the light at the end of the tunnel. Your hair will begin to look like it was before the treatment.

It even feels a little rougher, and you notice that it has less shine.


Day 70 to 90

Finally, your hair is back to the way it was!

Of course, these times are estimates because every treatment is different, and every hair reacts differently too.



Keratin treatments don’t disappear overnight because they last for approximately three to six months.

If you don’t like the results, don’t reactivate the keratin with the heat of the flat iron. Also, avoid washing your hair with a keratin shampoo. This way, you’ll soften the effects of the keratin treatment.
