You probably wanted to pamper your hair urgently. Can I guess how your hair was before the Brazilian Blowout? I think I won’t have to try very hard.

Your hair probably had untamable frizz. You were also probably tired of flat ironing it once a week.

It was also probably too dry, and you felt that moisturizing or natural oil masks were not enough.

So, you decided to invest your savings in a professional treatment like a Brazilian Blowout. And I think that’s a wise decision.

However, the treatment doesn’t end there.

So, for the sake of clarity, I’ll say it one more time and in capital letters.

Why is it so important to wait 72 hours to wash the hair after a Brazilian Blowout?

The treatment has a direct impact on the hair fiber. Small protective shields, namely the cuticles, cover it. The Brazilian Blowout process seals the cuticles to nourish and strengthen the hair core.

A flat iron between 190°C and 230°C is used to seal the cuticles. Once your stylist seals the Brazilian Blowout, she washes your hair to remove any product residue.

Finally, they’ll apply the Brazilian Blowout Ionic Bonding spray to make your hair shiny and silky.

So, when your stylist is done with the Brazilian Blowout, your hair is clean. 

Why do you want to wash it after 24 or 48 hours?


There’s an even more important reason why you should wait for 72 hours to wash your hair after a Brazilian Blowout.

Your innermost hair layers need that time for the Brazilian Blowout to settle.

 If you wash your hair before 72 hours, the cuticles could open and wash out the treatment. 

What are the consequences for your hair?

  • Frizz
  • Stiff hair
  • Dull hair
  • Brittle ends
  • Your curs could reappear if you had flat-ironed your hair.

In other words, your hair will look the same as it did before the Brazilian Blowout.

I think I’ve convinced you to wait 72 hours to wash your hair after the Brazilian Blowout. After all, no one likes to waste money.

Now, how should you wash it? That’s what I’ll talk about next.


How to wash your hair for the first time after a Brazilian Blowout?

shampoo and conditioner to wash hair after brazilian blowout
The Brazilian Blowout offers a complete line of shampoos, conditioners, masks, serum, revitalizers, and thermal protectants to maintain the treatment’s effects for longer.

  • If you can afford it, use the Brazilian Blowout shampoo and conditioner.
  • Otherwise, remember to use sulfate-free shampoos and conditioners.


Sulfates dry out your hair and weaken the cuticles. And it’s all about keeping cuticles closed and healthy for longer.

How to wash your hair for the first time?

  • Wet your hair with lukewarm almost cold water so that the cuticles remain closed.
  • Apply enough shampoo to cover your entire mane.
  • Massage your hair, lengths, and ends. Then, massage your scalp.
  • Rinse with plenty of lukewarm, almost cold water.
  • Apply conditioner to lengths and ends for five minutes.
  • Rinse with plenty of water and towel off the excess.


Although it isn’t necessary to apply heat, remember that the Brazilian Blowout is reactivated by the heat of the dryer or flat iron.

Therefore,  you can blow dry your hair after the Brazilian Blowout to reinforce the effects of the treatment.

If you want to flat iron your hair, always use a heat protectant. Remember that the cuticles open with heat and you could lose part of the Brazilian Blowout.



You should always wait for 72 hours to wash your hair after a Brazilian Blowout. This way, it’ll last up to six months.

Also, if you can’t afford the brand’s shampoo and conditioner, use sulfate-free products to wash your hair.
