Abstract

Background: All mammals have hair, a distinctive trait they share with no other species. In humans, it is a unique and priceless characteristic, especially in females, but its primary purposes are to protect the skin from mechanical insults and to facilitate the homeothermy; for example, eyebrows and eyelashes block objects from entering the eyes, while scalp hair shields the head and neck from sunlight, cold, and physical harm. Aim of the study: This research's objective is to assess the role of both trichoscopy and folliscopy in the diagnosis of cases of telogen effluvium (TE) and compare each method against the other. Subjects and Methods: One hundred adult participants with telogen effluvium were included in this study. They are diagnosed clinically and by trichogram as TE. All patients underwent trichoscopic and digital folliscopic evaluation. Results: The presence of more than 5% new regrowing anagen hair is a sure diagnostic sign of telogen effluvium by trichoscopy and folliscopy. Trichoscopic and folliscopic signs such as empty hair follicles, single hair follicles, and peripilar halo are also found in TE patients. Conclusion: The study has proved that both trichoscopy and folliscopy are highly accurate, highly sensitive diagnostic modalities in telogen effluvium, but trichoscopy has the advantage that it is easier and less time-consuming than folliscopy.
