Chemical depilatories that contain sulfides, thioglycolates, or enzymatic depilatory agents destroy the projecting hair shafts, causing minimal damage to underlying skin.

Hair is damaged by bleaching and highlighting, but it does not fall out as a result.
Bleach (sodium hypochlorite, NaOCl) degrades DNA through oxidative damage and production of chlorinated base products. Exposure to increasingly higher concentrations of NaOCl eventually causes cleavage of DNA strands, breaking it into smaller and smaller fragments.
