New to Alopecia Areata? There is a guide in the encyclopedia. Read the guide → Studysummary This study reports that yellow dots in a higher number per field of vision were the most consistent dermoscopic finding in severe cases of alopecia areata. Our plain-language summary of this paper — not a Tressless recommendation.
The study retrospectively analyzed 72 patients with alopecia areata (AA) to identify dermoscopic features and their correlation with disease severity. The most common findings were yellow dots (79.16%) and black dots (70.8%). Other notable features included short vellus hair (44.44%), broken hair (43.05%), and exclamation mark hair (31.9%). Yellow dots were most consistently found in severe cases, especially in progressive AA and alopecia universalis. Patients undergoing treatment showed increased numbers of short vellus hair and terminal hairs.
