Studysummary This study found that trichoscopy is a useful tool in differentiating between alopecia areta and trichotillomania on the eyebrows based on distinct hair and follicle features. Our plain-language summary of this paper — not a Tressless recommendation.

The study presented five cases of isolated eyebrow hair loss to highlight the trichoscopic features distinguishing alopecia areata (AA) and trichotillomania (TTM). Patients with AA exhibited yellow dots, vellus hairs, anisotrichosis, and empty follicular openings, while those with TTM showed split hairs, question mark hairs, broken hairs, flame hairs, and hemorrhagic areas. Trichoscopy proved to be a valuable tool in differentiating between AA and TTM on the eyebrows. The study emphasizes the importance of recognizing these features for accurate diagnosis and appropriate treatment.
