Trichoscopy in Alopecias: Diagnosis Simplified

The document reviewed trichoscopy, a non-invasive technique for diagnosing hair and scalp disorders, detailing its application in identifying various types of alopecia such as androgenetic alopecia, alopecia areata, telogen effluvium, tinea capitis, trichotillomania, lichen planopilaris, and discoid lupus erythematosus. It outlined trichoscopic signs like hair shaft diameter variation and yellow dots, which are indicative of specific alopecias. The review acknowledged limitations of trichoscopy, such as its sensitivity to external factors, but still highlighted its value in diagnosis and treatment monitoring, due to its ability to quickly examine large areas and its ease of use.
