Yellow dots, vellus hairs, anisotrichosis, empty follicular openings, and black dots were observed in the present study’s patients with AA. Split hairs, question mark hairs, broken hairs, flame hairs, black dots, hairs with different lengths, and hemorrhagic areas were found in the patients with TTM. Trichoscopy is a very useful and helpful technic in distinguishing AA and TTM on the eyebrows. ER -
