Surveys show that consumers with even severe adverse skin reactions to hair dyes only rarely contact the healthcare services. The frequency of hair dye-induced skin reactions in the consumer population is unknown. Objectives:An epidemiological investigation with the aim of establishing the proportion of hair dye-induced skin reactions was performed in a population-based sample. Methods:A representative random sample (n=4000) was taken of the Danish adult population. Personal interview questions were asked regarding adverse skin reactions to hairdyes,either compatible with a classical all ergic eczematous reaction with redness, scaling and itching or a severe allergic reaction with oedema of the forehead and face. The response rate was 65.2%. Results:A total of 184%of the male respondents and 74.9%of the female respondents had at some point dyed their hair. The median age at first hair dyeing was 16 years (range 1-80). Adverse skin reactions to hair dyes compatible with an allergic reaction were reported in 5.3%of individuals who had ever used hair dye. Of these, only 15.6%had been in contact with healthcare services after the hair dye reaction. Having had a temporary tattoo was not a significant risk factor for an adverse reaction to hair dyes. Conclusions:The rate of adverse allergic skin reactions to hair dyes was higher than expected from patch-test studies. Only by studying the clinical types of adverse reactions to hair dyes will it be possible to gather a complete epidemiological picture of the nature and extent of the problems related to hair dye ingredients.展开更多
