Evidence-Based Answer

The presence of tapering hairs on dermoscopy is the most useful finding to differentiate alopecia areata from other forms of alopecia (100% specificity). The presence of black dots, broken hairs, and trichorrhexis nodosa may also be diagnostically useful (SOR: C, 1 cross-sectional study and 1 case-control study, both at high risk of bias).
