Brazillian Keratin

Keratin is used as a straightening treatment in salons and home use. It can last from two to five months, which in most cases if a person chooses to wear their hair straight it could be a convenient option. I have heard some discouraging things about this product. For one, studies show that these straightening kits contain formaldehyde. Formaldehyde is a carcinogen that can lead to cancer.
