Allergens in Hairdresser Hand Dermatitis Masatoshi Itoh, Masaru Ishihara, Kumiko Hosono and Hiromi Kantoh Department of Dermatology, Toho University School of Medicine (Director: Prof. M. Ishihara) Makoto Nishimura Department of Pharmacology, Toho University School of Medicine (Director: Prof. R. Ito) During the 1982-1984 period, 19 hairdressers with hand and finger eczema were treated at our clinic. Open patch tests using hair colorings, cold permanent wave first and second solutions, shampoos, and hair rinses, which these patients had handeled, as well as closed patch tests using rubber hand gloves, paraphenylene diamine, and nickel sulfate were performed. The positive frequency was 56% to ppda, 28% to cold permanent wave first solution, and 9% to rubber gloves. Some of the patients with cold permanent wave first solution dermatitis exhibited positive reactions to ammonium thioglycollate solutions in open patch tests. It was concluded that open patch tests using cold permanent wave first solutions must be performed in order to determine the responsible agents in hairdresser patients exhibiting hand and finger dermatitis. It was confirmed using the guinea pig closed epicutaneous test that ammonium thioglycollate is a mild sensitizer.
