TLDR New dermoscopic criteria accurately diagnose and grade the severity of hair loss in androgenetic alopecia.
The document presents three studies proposing new dermoscopic diagnostic and grading criteria for androgenetic alopecia (AGA), a hair loss disorder. The first study involved 120 participants, with the diagnostic sensitivity and specificity of the AGA dermoscopic diagnostic criteria found to be 98.3% and 96.7% respectively. The second study involved 150 AGA patients and used the BASP classification as a gold standard for grading AGA severity. The accuracy of AGA grades 1, 2, and 3 according to dermoscopic grading criteria were 96%, 92%, and 100% respectively. The third study found that clinical grading tends to underestimate AGA severity, and dermoscopic grading complements clinical grading by corresponding to the BASP criteria. The new criteria could facilitate the diagnosis of AGA and reduce missed diagnoses.
