| Description |
Hairdressers have a high incidence of hand dermatitis, mainly irritant contact dermatitis caused by water, shampoo, and other chemicals. Glyceryl thioglycolate is a strong sensitizer; its use in permanent wave solutions was discontinued in Germany. Ammonium thioglycolate, also used in permanent wave solution, is a weak sensitizer. Dyes that cause allergic contact dermatitis include: p-phenylene diamine; 2,4-diaminotoluene; 2-nitro-4-phenylene diamine; 2-aminophenol; 4-aminophenol; 4-aminodiphenylamine; resorcinol; and henna. Other sensitizing agents include ammonium persulfate (bleaching), cocamidopropyl betain (shampooing), formaldehyde, preservatives, latex, thiuram compounds, nickel, and human dander.
