[Hormonotherapy in acute, idiopathic hirsutism, and seborrheic alopecia (author's transl)].

It has been established that, through skin responds to circulating androgens, it can also produce androgens from precursors. Therapy can address either of the two following physiopathological steps: the secretory step can be countered by replacement or suppressive therapy which is now fairly well mastered; the target-organ step opens new possibilities concerning receptor abnormalities and receptor control. The medical literature was reviewed for data on hormonal therapy for women with acne, idiopathic hirsutism and seborrheic alopecia, three conditions which are usually only partially improved by cosmetic treatment.
