TLDR Trichoscopy helps diagnose hairline recession causes in Egyptian women, with androgenetic alopecia being the most common.
The study involving 200 Egyptian female patients aged between 15 and 65 years used trichoscopy to identify the causes of frontal hairline recession. Androgenetic alopecia (AGA) was the most prevalent cause, affecting 50% of the patients, particularly in the older age group. Trichoscopic features such as hair diameter diversity, single-hair pilosebaceous units, and yellow dots were indicative of AGA. Traction alopecia (TA) was characterized by vellus hair and perifollicular casts, while trichotillomania (TTM) showed broken hairs at various levels and black dots. Frontal fibrosing alopecia (FFA) presented with perifollicular scaling and absence of hair follicles. The study highlighted the importance of trichoscopy as a noninvasive tool for diagnosing different types of hair loss and introduced new trichoscopic signs that could serve as prognostic markers.
