A Single-Center, Prospective, Open-Label, Pilot Study of the Safety, Local Tolerability, and Efficacy of Ultraviolet-C (UVC) Phototherapy for the Treatment of Great Toenail Onychomycosis

The document presents a study on the use of trichoscopy for diagnosing hair loss in adult female patients. Trichoscopy, a noninvasive technique using videodermoscopy, was performed on 75 female patients with different types of hair loss, including alopecia areata and androgenic alopecia. The study found specific trichoscopic features for alopecia areata, such as micro-exclamation mark hairs, and characteristics for androgenic alopecia, like high hair shaft diameter diversity. The technique allowed for in vivo observation without the need for hair removal. The conclusion suggests that trichoscopy is a useful, fast, and noninvasive diagnostic tool for hair loss, and further studies are needed to establish clear criteria for diagnosing specific hair loss diseases. No commercial support was identified for this study.
