    TLDR Trichoscopy helped diagnose and treat a child's fungal scalp infection by spotting specific hair shapes.
    The document reports a case study of a 6-year-old African female child with non-scarring alopecia and scaling, which had been present for 2 months. Trichoscopy, a dermoscopic examination of the hair and scalp, revealed the presence of comma hairs and corkscrew hairs, which led to the diagnosis of Tinea Capitis (TC), a fungal infection caused by Trichophyton tonsurans. Treatment with griseofulvin resulted in complete clinical and dermoscopic resolution of the alopecia. The study highlights the utility of trichoscopy in diagnosing hair and scalp diseases, with comma-shaped hairs being a marker of TC and corkscrew hair indicating a more advanced stage of the infection. The document emphasizes that trichoscopy can aid in diagnosing various conditions such as Androgenic alopecia, Alopecia areata, Lichen planopilaris, and Trichotillomania by identifying specific hair and scalp changes.

      TE (telogen effluvium) is often misunderstood and is triggered by severe stress or trauma, not minor daily inconveniences. Most hair loss cases are due to male pattern baldness (AGA), and treatments like Minoxidil and finasteride can help.
