Do hair porosity products need FDA approval?

The FDA classifies most hair care products — conditioners, masks, leave-ins — as cosmetics, not drugs, so pre-market approval is not required. However, they must be safe for intended use, properly labeled with an INCI ingredient list, and free from prohibited substances. If a porosity product makes drug claims (e.g., 'repairs damaged DNA'), it may be regulated as a drug. A cosmetic chemist on AJ Cosmo Labs can guide compliant claim language.
