title: 3 percent topical minoxidil compared with placebo for the treatment of chronic severe alopecia areata.
abstract: The efficacy of a 3 percent topical minoxidil solution (2,4-diamino-6-piperidinopyrimidine-3-oxide) in a propylene glycol-water-ethanol base applied twice daily for one year to half the scalp was evaluated in patients with severe chronic alopecia areata. A randomized, double-blind, bilateral comparison-controlled study design was used. Of the twenty-one patients, thirteen were women and eight were men; their ages ranged from nineteen to fifty-five years. All the patients had alopecia totalis or alopecia universalis, except for two who had lost two-thirds of their scalp hair. The mean disease duration was 11.5 years (range, one to forty years). Transient regrowth of sparse vellus hair occurred in twelve patients, bilaterally in eight, but it was not significant in any. No cosmetically acceptable results were achieved. No significant side effects were noted, except for a moderately severe bilateral dermatitis in one patient. The results indicate that 3 percent topical minoxidil solution is ineffective as treatment for severe chronic alopecia areata.
