A randomized comparison of three conventional modes of treatment of psoriasis of the scalp.

Three conventional treatments of scalp psoriasis were compared in a randomized, blind, uncontrolled clinical trial in 30 patients at a psoriasis day-care centre. Triple gel (the sequential application of Keralyt, Estar, and Topsyn gels), 10 percent salicylic acid in Sofsyn oil, and 10 percent salicylic acid in mineral oil were compared. There were no statistically significant differences among the three treatments in terms of clinical efficacy. Therefore, on the basis of lowest cost and highest patient acceptance, 10 percent salicylic acid in mineral oil is the preferred treatment.
