Background: hairdressers have a high risk to develop allergic contact dermatitis (ACD) because of long-term exposure to irritating and sensitizing substances. Therefore, it is necessary to protect skin with chemical rubber or natural rubber latex gloves, which can cause allergy due to the presence of antioxidant or vulcanizing additives, and natural rubber latex proteins. Objective: the aim of this study was to verify the prevalence of sensitivity to rubber additives and latex in a population of hairdressers with hand and/or forearm contact dermatitis. Materials and methods: from March 2003 to November 2004, a total of 170 hairdressers were studied in 14 Allergologic Dermatologic Italian Centers with the following screening: SIDAPA standard series patch test, rubber series, hairdressers series plus latex, and skin prick test with latex. Results: the following substances gave the highest number of positive patch test reaction: nickel sulphate (37.1%), paraphenylendiamine (36.5%), ammonium persulphate (16.5%), disperse orange 3 (14.7%), paratoluendiamine sulphate (14.7%). Rubber additives delayed allergy occurred in 21.7% of subjects, with a higher number of positive reaction for carba mix, thiuram mix and diphenylguanidine. Latex proteins IgE-related allergy was observed in 12.5% of 136 hairdressers who were skin prick tested with latex. Conclusions: the results confirm that ACD, which occurred in 54.1% of evaluated subjects, is the most frequent cause of cutaneous disease in hairdressers. Latex proteins Ig-E related allergy is considerable (12.5%): high frequency contact exposure to latex seems to be a risk factor for the development of latex allergy in these workers.
