Keratin hair straighteners, like the Brazilian Blowout, are “unsafe” for use at home or salons, according to the industry’s Cosmetics Ingredient Review panel.
Expressing concern that the combination of formaldehyde and heat in hair-straighteners like Brazilian Blowouts “may not be safe” even in salons with ventilation, the Cosmetics Ingredient Review panel has voted to label use of these products “unsafe.”
“Based on the unique circumstance of formaldehyde/methylene glycol use in hair smoothing products intended to be heated, the likely production of substantial amounts of formaldehyde gas, and the absence of any assurance that adequate ventilation could/would be available, the Expert Panel determined such use of formaldehyde and methylene glycol to be unsafe,” the panel writes.
