The purpose of this study was to assess the effectiveness of different treatments in patients with alopecia totalis or universalis who did not respond to sensitizing therapies. Twenty-six patients, who had been receiving sensitizing therapy for at least 1 year without any response, were randomly assigned to receive the following treatments: topical 10% cyclosporine in oily solution (eight patients), PUVA (eight patients), and intravenous thymopentin (ten patients). None of them had any acceptable regrowth after at least 6 months of treatment. Our results suggest that other treatments are not useful in patients with 100% hair loss who fail to respond to sensitizing therapies.
