New treatment for seborrheic alopecia: the ligature of the arteries of the scalp

Abstract

Bilateral ligature of the superficial temporal arteries and of the posterior auricular arteries is proposed as a treatment for seborrheic alopecia. The arterial circulatory dynamics are, thus, replaced by capillary circulatory dynamics. Hypoxia is produced which inhibits enzymatic systems and lessens nocuous action of androgen and lipid factors on the pilosebaceous effectors. The histologic study shows that the production of sebum is greatly reduced and the condition of the hair follicle is strikingly improved.
