In the early 2000s, the Food and Drug Administration began receiving complaints from consumers and salon professionals regarding their safety in using products containing formaldehyde (including the Brazilian Blowout solution). In 2010, the FDA enlightened the public about the potential dangers of using formaldehyde-containing products, including the Brazilian Blowout straightener, and in 2016, the FDA deemed formaldehyde-containing hair straighteners unfit for use.
