First of all, let’s establish some essential information about these treatments!

  • Brazilian Blowout is actually a trademark – “Brazilian Blowout™”! Although salons use the name to refer to their smoothing treatments, they normally don’t use the original product.
  • Keratin treatments, however, are those smoothing treatments that are mainly composed of keratin. Therefore, there are several different keratin treatments, from many brands.

Although we are going to talk about the differences between them, we need to acknowledge the fact that these hair procedures have a main aspect in common: they achieve a similar effect – smooth and shiny mane – by creating a layer of protein around the hair fiber. Also, Keratin treatments and Brazilian blowouts use some chemicals on their formula, which means you’ll be exposed to them to some degree during the heat activation!

Besides the similarities above, after going through one of those treatments, you’ll have to cut back a bit on hair washing! That’s because you want the effects to last as long as possible, ok? Now, let’s move on to the differences…


Each treatment works best in different hair types. If your hair is curly, thick, or super voluminous, you should opt for a keratin treatment! That is because this type of procedure leaves your hair straighter and with less volume, making it more manageable! 

However, if you want to keep your hair voluminous but just decrease the amount of frizz in it, a Brazilian Blowout is the one for you! It’s also recommended for those with fine or already straightened hair since it’s less powerful than Keratin treatments. Also, if you have done a Japanese straightening procedure before, stick to the Brazilian Blowout.


A very noticeable contrast between these two treatments is the time they take to be performed! That’s also related to the fact that Keratin treatments can be done at home, while Brazilian Blowouts are usually done at a hair salon. Because of that, the former can take up to three hours to be completed, while the latter takes from one to two hours!


As always, after going through a hair treatment, there are some precautions you should have in order to get the best results possible! And here lies another divergence between the treatments we are talking about!

After the keratin treatment, you should stay 3 days without washing your hair to keep the product active in it. You should also avoid tying your hair and touching it! Meanwhile, with a Brazilian Blowout, the moment you leave the hair salon, your treatment is already complete, with means you can wash your locks whenever you want! There’s also no problem in styling your hair!
