As a hairstylist, I can tell you that these straightening products (keratin treatments, brazillian blowouts) claim to be formaldehyde free. However, they contain GLYOXYLIC ACID. When this acid is heated to 450 dregrees, which the treatment requires a 450 degree iron to passes through the hair, it emits a chemical gas.

This chemical gas is formaldehyde.
