Tinea capitis
From dermoscopedia
The most characteristic trichoscopic findings of tinea capitis include comma hairs, corkscrew hairs, zigzag hairs and Morse code hairs (1-3) (4, 5) (6-8). Moreover black dots and broken hairs are frequently detected (9). Other trichoscopic features include bent hairs, i-hairs, block hairs and perifollicular/interfollicular scaling (10, 11).
The successful treatment of tinea capitis is characterized by reduction of short broken hairs, corkscrew hairs and zigzag hairs and latter comma hairs and black dots (10).
