TLDR Trichoscopy helps diagnose different hair diseases effectively.

Trichoscopy was a valuable diagnostic tool for differentiating common hair diseases by examining follicular openings, hair shafts, and perifollicular epidermis using a dermascope. It was particularly useful for diagnosing early androgenetic alopecia, distinguishing it from telogen effluvium, and differentiating between scarring and nonscarring alopecias. The article summarized the knowledge of abnormal appearances in trichoscopy and the characteristic features of prevalent hair conditions.
