I. INTRODUCTION

Hairdressers undoubtedly have an increased risk of developing an occupational dermatitis. Continual exposure to numerous irritants and allergens as well as to frictional forces and microclimatic changes are some of the factors causing hand dermatitis. In many patients the condition worsens progressively, in spite of correct diagnosis and various measures of treatment, leading to repeated sick leaves and, finally, surrender of the profession. The costs for medical care, and particularly for the retraining of the (usually) young patient, are substantial. The socioeconomic aspect, together with the personal suffering from the disease, and certain clinical features, justify a special chapter in a book on hand eczema.
