Question: how soon can i wash my hair after brazilian blowout?
Answer: "After you get a keratin treatment, you don't have as many options," says Matos. "You can't tie it back in a ponytail or clip, you can't style it, and you can't wash it for the three or four days that follow. With the Brazilian Blowout, you get it done, your stylist rinses it out, and that's it.
