BACKGROUND: The pathogenesis of androgenic alopecia is not fully understood. A
microbial-driven inflammatory reaction abutting on the hair follicles might participate in
the hair status anomaly. OBJECTIVE: The aim of our study was to determine if ketoconazole
(KCZ) which is active against the scalp microflora and shows some intrinsic
anti-inflammatory activity might improve alopecia. METHOD: The effect of 2% KCZ shampoo
was compared to that of an unmedicated shampoo used in combination with or without 2%
minoxidil therapy. RESULTS: Hair density and size and proportion of anagen follicles were
improved almost similarly by both KCZ and minoxidil regimens. The sebum casual level
appeared to be decreased by KCZ. CONCLUSION: Comparative data suggest that there may be a
significant action of KCZ upon the course of androgenic alopecia and that Malassezia spp.
may play a role in the inflammatory reaction. The clinical significance of the results
awaits further controlled study in a larger group of subjects.
