    TLDR Dermoscopy is a useful tool for diagnosing and managing alopecia areata.
    The study on the utility of dermoscopy in alopecia areata (AA) examined 66 patients and found that dermoscopy was a valuable non-invasive tool for diagnosing and managing AA. The most common dermoscopic features identified were yellow dots (81.8%), black dots (66.6%), broken hairs (55.4%), short vellus hair (40.9%), and tapering hairs (12.1%). These features helped differentiate AA from other types of hair loss and were consistent across different types and severities of AA. The study concluded that dermoscopy could enhance the accuracy of clinical diagnosis and aid in monitoring treatment response, with yellow dots being the most sensitive marker.
