An extremely popular hair treatment, that it seems like everyone is talking about has been found to contain formaldehyde by the Occupational Safety and Health Administration. The product is something called Brazilian Blowout.

According to the OSHA, who does tests to make sure products are safe to use, the Brazilian Blowout contains an unsafe level of the possible carcinogen, formaldehyde. Some reports are suggesting that it may contain as much as 5% formaldehyde. Laws state that products may not contain any more than 0.1% of the harmful ingredient.

Brazilian Blowout says that their products do not contain formaldehyde, and that the OSHA’s test results are incorrect. They claim that the samples used for testing were not from the company itself but from a salon.

Women have been reporting that they have gotten nosebleeds, burning skin, burning eyes and had difficulty breathing after use of the hair product. The company says that the product only contains amino acids and not the harmful formaldehyde. Until more studies can be completed, it is suggested that women wear masks while using the hair product.
