TLDR A 6-year-old boy's leg hair loss was due to friction from sitting cross-legged, and it usually resolves on its own.
A 6-year-old boy presented with patchy hair loss on his lower limbs, diagnosed as frictional alopecia, likely due to cross-legged sitting and rubbing. Dermoscopic evaluation showed decreased hair density, broken hairs, and signs of microtrauma. The condition, typically seen in middle-aged males, is rare in children and often self-resolving. Habit reversal and counseling were recommended. The case highlights the need for further research on pediatric frictional alopecia, as it is often underreported due to its benign nature. There was no family history or thyroid disorder, but a possible association with atopy was noted.
