The Brazilian Blowout is one of the hottest trends in hair straightening. It promises long-lasting results and claims to be free of harmful chemicals. But it is reportedly causing problems for some women, including difficulty breathing, nosebleeds and burning eyes and skin.
Government scientists who tested the product discovered small amounts of formaldehyde in the samples. The chemical is a possible carcinogen.
The maker of the Brazilian Blowout says the product is made of amino acids and does not contain formaldehyde.
Until more testing is done hair stylists are advised to use goggles and masks while using the product. A Brazilian Blowout costs between $200 and $500.
