Objective. Brittle nails are a common complaint affecting 20% of the general population. The aim of this study was to evaluate the efficacy of biotin in the treatment of idiopathic nail brittleness. Methods. Biotin 10 mg/day per os for 3 to 6 months was administered to 20 patients affected by onychoschizia lamellina who had been unresponsive to topical treatments. All the patients were evaluated 3, 6 and 9 months after starting therapy. Results. After 6 months of therapy 17 patients showed a complete clearing of nail fragility. None of our patients experienced side effects. Conclusions. A daily oral dose of 10 mg of biotin provides an effective therapy for patients affected by brittle nails.
