Traction alopecia is hair loss caused by repeated pulling on the hair shaft, usually from tight ponytails, braids, buns, extensions or headwear. It typically appears along the hairline and temples where tension is greatest.
Caught early, it is reversible by changing styling habits. Prolonged traction can permanently scar follicles, after which regrowth is limited. A doctor can distinguish traction alopecia from other causes and advise on scalp care and treatment where follicles are still active.
