My experience in the Brazilian Keratin Straightening
I myself personally experienced the Brazilian Keratin straightening. my hair before straightening were in terrible shape (I paint in a blond, using blondish, and moreover, without laying looked like a dandelion, sticking out in all directions). result exceed all my expectations! hair after straightening become smooth, shiny and healthy appearance get! but did not lasted long, just a month since I swam in the sea. but no one warned me that salt is anterior to the Brazilian straightening. winter will repeat the procedure again!
