Hand dermatitis in hairdressers is caused by a variety of factors. Imp
ortant are the sensitizing and irritant capacities of some hair-cosmet
ic ingredients. unsafe packaging which causes contamination of the han
ds, work tables and instruments with hazardous chemicals, absence of p
rotection with adequate gloves and ignorance of safe handling of these
chemicals. A strategy is proposed, based on improvement of the safety
of ingredients and packaging, use of vinyl gloves and introduction of
safe hairdressing procedures. Introduction of this strategy in hairdr
essing salons with 16 cases of moderate to severe contact dermatitis r
educed the number of cases of active dermatitis to 3 in 4 months. The
value of pre-employment screening is discussed and the necessity of co
operation of centers of occupational dermatology is emphasized.
