Abstract
Twenty-five patients with alopecia totalis (AT) or alopecia universalis and 124 patients with alopecia areata (AA) were treated with photochemotherapy, combining topical 8-methoxypsoralen (8-MOP) with UV irradiation of the scalp at a phototoxic dose. The mean energy required was 15 J/cm2 for AA and 42 J/cm2 for AT. Ninety-four patients had multiple bald patches and 12 with AT had complete or > 50% hair regrowth. Positive treatment results did not seem to depend on the age of onset or the duration of the disease. Few side-effects of topical psoralens plus UVA (PUVA) treatment were noted, except a for few days of slight erythema caused by the high dose of UV.
