Abstract
|
|
|
|
Trichorrhexis nodosa is the most common hair shaft anomaly in which there is a chemical or physical traumatic injury, characterized by the development of node-like swelling, fragility of the shaft and paint brush effect on the side of the fracture. We report two cases of trichorrhexis nodosa in 15-year-old girl and 16-year-old-boy, occurring as results of repetitive hot-comb straightener and excessive scratching. Scanning electroscopic findings are typical to trichorrhexis nodosa.
