With so many celebrity endorsements over the years, it’s no surprise that Brazilian blowouts and keratin treatments have taken off in popularity. They both have similar benefits, the chief of which is smoothing your hair for a sleeker look.

Because of this main similarity, there are a lot of people wondering what the differences are between these two treatments and which of the two they should get. We’ll cover their similarities and differences, the best candidate for each, and some responses to other frequently asked questions.

Similarities Between Brazilian Blowout and Keratin Treatment

Both a keratin treatment (KT) and a Brazilian blowout (BB) make your hair look shinier, smoother, and possibly straighter. They can sometimes get confused with a Japanese Straightening Perm, which is a little different because it permanently changes your hair structure to make your hair straight; the two types of hair treatments we’re discussing are temporary. 

Both the BB and the KT develop a protein layer that surrounds your hair shaft, in turn smoothing your hair cuticle. That leaves your hair looking smooth, shiny, and healthier.

One of the main aspects that clients like about both processes is that they keep humidity from changing your hair and causing frizziness.

The smoother your hair is, the more it reflects the light, appearing more beautiful and making your hair easier to manage. Of course, this makes styling your hair a breeze on a day-to-day basis.

There are, however, some dangerous chemicals used on your hair during these treatments. Both the Brazilian blowout and the keratin treatment use formaldehyde (plus other types of aldehydes) on your hair while applying heat.

You won’t be able to wash your hair as often as you may have before these processes once they are complete. Otherwise, you can unintentionally wash the treatments out of your hair. For longer-lasting results, you should use a sulfate-free shampoo.
