Studysummary In this study, the authors evaluated 200 Egyptian children with focal non-cicatricial alopecia, finding that alopecia areata (42%) and tinea capitis (40.5%) were the most prevalent causes. Trichoscopy identified unique features for each condition, enhancing diagnosis and management. Our plain-language summary of this paper — not a Tressless recommendation.

The study evaluated 200 Egyptian children aged 2 to 18 years with focal non-cicatricial alopecia using trichoscopy, a noninvasive diagnostic tool. The most common diagnoses were alopecia areata (42%) and tinea capitis (40.5%), followed by trichotillomania (8%) and tractional alopecia (7%). Trichoscopy identified specific features for each condition, such as exclamation mark hair in alopecia areata and comma hair in tinea capitis, aiding in accurate diagnosis and management. The study concludes that routine use of dermoscopy enhances diagnostic capabilities for scalp and hair disorders beyond simple clinical inspection.
