One-page reference card for perm & relaxer chemical safety in salons.
Permanent-wave and relaxer solutions use strong reducing or alkaline agents to break and reform disulfide bonds in hair keratin[1]. Thioglycolate perms (pH 9-9.6), sodium hydroxide relaxers (pH 12-14), and ammonium bisulfite alternatives each carry distinct hazard profiles. In any country, the cosmetics safety regulator sets concentration limits and requires GHS-compliant labelling[2].
