title: Generalized Hypertrichosis Induced by Topical Minoxidil in an Adult Woman.
abstract: Hypertrichosis is a common side effect of topical minoxidil and has been reported to occur mainly close to the areas of application. In this paper, we present a case of a 26-year-old woman who developed generalized hypertrichosis 8 weeks after treatment with 5% topical minoxidil solution for alopecia areata. Generalized hypertrichosis is a rare side effect and has been described mainly in children and adolescents. Even though minoxidil is commonly prescribed for alopecia areata, there is insufficient evidence to support its systematic use and the occurrence of adverse effects should prompt drug interruption. Nonetheless, topical minoxidil has been shown to be a safe medication for adult patients, and we believe that the present case was an isolated one, possibly resulting from the misuse of the drug.
