    Studysummary This study found that trichoscopy can rapidly and noninvasively diagnose tinea capitis and alopecia areata in pediatric patients by identifying specific hair patterns associated with each condition. Our plain-language summary of this paper — not a Tressless recommendation.
    In the 2014 study involving 40 pediatric patients, trichoscopy was utilized to distinguish between tinea capitis and alopecia areata by identifying unique trichoscopic features. The study found that comma shaped hairs, corkscrew hairs, and zigzag shaped hairs were diagnostic of tinea capitis, while yellow dots, exclamation mark hairs, and short vellus hairs were specific to alopecia areata. Black dots were a common feature in both conditions but were not specific to either. The study concluded that trichoscopy is an effective noninvasive diagnostic tool for these conditions in children, with certain trichoscopic features being characteristic of each condition.
