Among men, the most frequent contact allergens are perfumes (fragrance mix and balsam of Peru). Considering that the main cause of nickel allergy is ear‐piercing, shaving with a razor blade might be the cause of perfume contact allergy, by creating small wounds that increase the penetration of applied perfume substances derived from soaps, shaving foams and after‐shave lotions. 19 males with contact allergy to fragrance mix and/or to balsam of Peru were interviewed about their shaving habits by letter. 17 responded (89%), of whom 12 (71%) had been using razor blades continuously for a period of at least 1 year. At our clinic, the frequency of razor blade usage was found to be 45% in patch tested men without perfume contact allergy. When comparing the frequencies of razor blade usage among patch tested men with and without perfume contact allergy, there was a statistically significant over‐representation ( p = 0.047) among those with perfume allergy. The risk of perfume allergy when using razor blades was found to be 2.9 (odds ratio).
