Monilethrix - Improvement by hormonal influences?

Monilethrix is a hereditary hair disorder that occurs monosymptomatically o r as a monilethrix syndrome combined with other ectodermal anomalies. We re port two siblings with the triple combination of monilethrix, keratosis pil aris, and koilonychia. In one of our patients, the hair disorder improved, with maximum hair growth up to 8 cm in length after her first menstrual per iod occurred, suggesting that hormonal influences may improve the hair diso rders in monilethrix.
