Background: Tinea capitis is the most common pediatric dermatophyte infection. Trichoscopy aids in the rapid diagnosis and allows prompt treatment, preventing horizontal transmission. Objectives: The objective of this study is to document the trichoscopic features of tinea capitis and evaluate its correlation with clinical type, microscopic form, and mycological culture and propose diagnostic trichoscopic criteria.Materials and Methods: Trichoscopy was performed, after taking consent in 98 participants (<18 years) of tinea capitis diagnose by hair root and scalp scraping examination for hyphae positive on potassium hydroxide mount microscopy or culture positive on SDA media. The comparison of observed trichoscopic features, with the clinical type, pattern of invasion, and etiological agent was carried out. Results: The most common clinical variant was black dot, and etiological agent was Trichophyton violaceum. The following trichoscopic features were noted: black dot, comma, short broken, corkscrew, horse-shoe, zigzag hair, and perifollicular scaling. Perifollicular scaling was significantly common in gray-patch variant, whereas comma, black dot, horse-shoe hair, and perifollicular scaling were noted in black-dot variant. Comma, corkscrew, and zig-zag hair were significantly present in endothrix form, whereas perifollicular scaling was evident in ectothrix form. Combining perifollicular scaling with comma hair, short broken, and black dot hair achieved a diagnostic sensitivity of 98.97%. Conclusions: Trichoscopy by evaluating for the combination of perifollicular scaling and 3 dystrophic hair (comma hair, black dot, and short-broken hair) is a good diagnostic tool for tinea capitis. Horse-shoe hair a novel finding, not hitherto reported in the literature requires validation in future studies.
