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).

Moreover, blood extravasations may be observed (12).

Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions of tinea capitis. Pediatr Dermatol. 2012;29(2):223-224.

Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. of tinea capitis. JAMA Dermatol. 2015;151(3):308-310.
