Many studies have been performed regarding the efficacy of psoralen plus UV-A (PUVA) in the treatment of alopecia areata, and the initial response rate varies from 20-73%. The relapse rate, unfortunately, is high (50-88%). Most patients relapse within a few months (mean 4-8 mo) after treatment is stopped.
