Luckily, not all of this fall’s hair trends need sleek straight hair since the popular and pricey salon treatment for turning frizzy hair lustrous, Brazilian Blowout, recently got slapped with its first official warning letter by the U.S. Food and Drug Administration. The agency claims the Brazilian Blowout “contains a deleterious substance that may render it injurious to users under the conditions of use prescribed” and is “mislabeled” because it claims to be formaldehyde-free when FDA tests show that’s not the case.
What’s the problem?
Tests by the FDA show anywhere from 8.7 percent to 10.4 percent of the straightening product contains methylene glycol, a liquid form of formaldehyde that when heated with a blow dryer and then a flat iron as per the product’s instructions releases formaldehyde into the air. Formaldehyde is a dangerous known carcinogenic chemical that affects the mucous tissues lining the respiratory tract and eyes.
