What are the characteristics of monilethrix?

Monilethrix is characterized by a beaded appearance of the hair due to periodic thinning of the shaft. This condition results in hair fragility and patchy dystrophic alopecia (hair loss). The term monilethrix is derived from the Latin word monile, which means necklace, and the Greek word thrix, which means hair. This term describes the resemblance of the hair to a string of beads or a necklace.[1]
