Monilethrix is the technical term for what hair condition?

• A. Brittle hair
• B. Curly hair
• C. Beaded hair
• D. Straight hair

Answer: (C)

Monilethrix is a hereditary hair shaft disorder characterized by a beaded, necklace-like appearance along the hair shaft. The hair shows regular constrictions between thicker nodes, giving a bead-like pattern that makes the term beaded hair an exact description. This beaded pattern is the defining feature, with hair often breaking easily at the constrictions as a common accompanying trait. The name itself comes from Latin roots meaning “necklace hair,” which helps recall why beaded hair is the correct description. While brittleness or abnormal texture can occur, they describe effects rather than the distinctive pattern that defines the condition. It’s not about curl or straightness, but the bead-like shaft appearance.
