Trichoscopic Findings in Androgenetic Alopecia

The study "Trichoscopic Findings in Androgenetic Alopecia" examined 120 patients with androgenetic alopecia using trichoscopy, a non-invasive technique for evaluating hair loss. The most common trichoscopic features found were hair shaft thickness heterogeneity, yellow dots, perifollicular discoloration, and an increased number of vellus hairs. The study also compared 104 patients with Androgenetic Alopecia (AGA) to 80 healthy subjects, finding a significantly increased number of yellow dots, pilosebaceous units with only one hair, and units with perifollicular hyperpigmentation in AGA patients (p<0.05). Additionally, AGA patients had a significantly higher percentage of thin hairs (<0.03 mm) than healthy controls (p<0.05). The study concluded that trichoscopy is a useful tool for diagnosing and monitoring AGA, recommending regular clinical and trichoscopic follow-ups.
