West Coast fans of the Brazilian Blowout smoothing treatment are about to find out exactly what goes into their favorite salon service. A recent investigation by the state of California found that Brazilian Blowout’s Acai Professional Smoothing Solution contains around eight percent formaldehyde, the same percentage found in the embalming fluid used by funeral homes. Formaldehyde is a known carcinogenic, and salon specialists who work with the products frequently are especially at risk for exposure. Last week, the California Attorney General filed an injunction against Brazilian Blowout, seeking to require health warnings on the line, WWD reports. And meanwhile, the Occupational Safety and Health Administration issued a hazard alert yesterday, warning salon-goers about the health risks associated with using the products. Tell us, do these findings make you think twice about the treatment?
