Keratin Treatment
A keratin treatment, also known as a Brazilian blowout, is typically performed in professional hair salons to straighten the hair. It can also reduce frizz and make your hair look glossy. The results can last up to six months after the procedure. In a keratin treatment, the stylist will wash your hair before brushing the treatment and letting it sit on your hair for around 30 minutes. It can be applied to either dry or wet hair. After that, the hair is flat ironed in small parts to keep the treatment sealed in. It would take a few hours to complete the entire process. [2]
