New Study Finds Hidden Formaldehyde in More Hair Straightening Products
A new study published by ChemRisk LLC, has found that airborne formaldehyde levels associated with some keratin hair straightening products (including Brazilian Blowout) exceeded safe exposure levels set by the U.S. government in controlled tests. Formaldehyde is a known human carcinogen and has repeatedly been found in dangerously high levels in the popular hair straightening product Brazilian Blowout for the past year.
According to the study, three quarters of the hair products tested contained more formaldehyde than the products claimed. The study tested four popular keratin-based hair products, including the Brazilian Blowout Acai Professional Smoothing Solution, Global Keratin Juvexin Optimized Functional Keratin, Coppola Keratin Complex Blonde Formula and La-Brasiliana Escluso Keratin Treatment. Only La-Brasiliana tested formaldehyde-free.
Global Keratin was the only tested product to mention the presence of formaldehyde on the label, but the ChemRisk study found the product contained more than twice the amount claimed: 8.3 percent, well above the .01 percent level set by the industry, which requires disclosure and safety hazard information. Brazilian Blowout was labeled formaldehyde-free but contained the highest levels, 11.5 percent.
