Ciclopiroxolamine (CPO) and Zinc Pirythione (ZP) antifungals are efficient at treating scalp seborrheic dermatitis.This multicentre, single-blind, clinical study was conducted to evaluate the efficacy of a shampoo containing the 1.5% CPO/1% ZP association compared to the vehicle shampoo and to 2% ketoconazole foaming gel in the treatment of seborrheic dermatitis.In 189 patients randomised to apply 1 of the 3 products twice a week for 28 days, the global lesional score, erythema, pruritus, global efficacy, quality of life (SF12 and DLQI questionnaires) and tolerance were measured at 0, 7, 14 and 28 days.The 3 products reduced lesional score, erythema and pruritus from day 7 (p < 0.0001). The 2 antifungal treatments were significantly more efficient than the vehicle in reducing lesional score, erythema and pruritus at day 14 (p < 0.0001). At day 7, the CPO/ZP shampoo was more efficient in reducing pruritus than ketoconazole gel and vehicle (p = 0.032 and p < 0.001, respectively). The global efficacy of the 2 antifungal treatments assessed at day 28 by both investigator and patient was significantly better than that of the vehicle. Only the CPO/ZP shampoo improved all DLQI questionnaire dimensions.The CPO/ZP shampoo was as rapid and efficient as ketoconazole gel in SD treatment.
