The aim of this study was to compare, by stratification, subgroups of hairdressers. Three groups were considered: Group I (102 persons) consisted of hairdressers reporting skin affection at the time of completing an earlier mailed questionnaire (point prevalence). Group II reported exanthema prior to completing, while group III reported not having had exanthema at all (51 and 50 persons, respectively). No significant difference was found between these groups with regard to age and duration in work. The mean number of months since start of disease was significantly higher for group I (64 (range: 0.5-552)) than group II (7 (range: 0.6-38)). The frequency of atopic dermatitis was 12.7% (C.I: 6.3-19.2) in group I, compared with 3.9% (C.I: 0.0-9.2) in group II and none in group III. This difference between groups was significant. A significantly higher extent of sick leave was found in group I, compared to group II.
