Background: The aim of the study was to assess the effectiveness of a UV-B-comb on scalp psoriasis versus betamethasone valerate solution.
Material and methods: Of 44 adult patients with scalp psoriasis, 22 were treated with a dermalight 80 psoracomb and 22 with betamethasone valerate solution, five times a week for three weeks.
Results: No difference in effect was found at the end of treatment. Two weeks after end of treatment a higher proportion of patients treated with UV-B-comb (7/22) had remained in remission than those treated with betamethasone valerate solution (3/22; p < 0.05).
Interpretation: Treatment with a UV-B-comb offers a good alternative to topical corticosteroids for patients with scalp psoriasis.
