Monilethrix Treated with Minoxidil

This study reports on the treatment of four patients with Monilethrix, a rare hair disorder, using topical minoxidil 2% for one year. The treatment led to an increase in normal hair shaft without any side effects in all patients, suggesting that topical minoxidil 2% could be considered a good therapy to treat Monilethrix. The study also provides clinical observations and videodermatoscopic and ultrastructural features of Monilethrix, as well as a discussion on the etiopathogenesis of the disorder and the action mechanism of minoxidil. The authors suggest that topical minoxidil could be a good alternative to stabilize and support the disease without having any side effects.
