| Summary: | Abstract Introduction Alopecia areata (AA) is a non-scarring autoimmune disease characterized by patchy hair loss. The aim of this study was to validate a novel trichoscopic scoring tool, the Severity TRichoscopy Index for Alopecia Areata (STRIAA), for rapid assessment of AA severity. Methods Anonymized images from 340 patients were scored by two independent raters who analyzed four scalp areas (vertex, occipital, and left and right parietal) for trichoscopic signs: black dots, yellow dots, exclamation mark hairs, broken hairs, and short vellus hairs. Scores (0–3) were assigned according to the number of trichoscopic signs per area, resulting in a total STRIAA score out of 60. Results STRIAA showed high interrater reliability (Cronbach’s alpha 0.99) and significant correlation with the Severity of Alopecia Tool (SALT) score (p < 0.001). Yellow and black dots were significantly associated with the SALT score. Conclusions The STRIAA provides a rapid and comprehensive assessment of AA severity, complementing current assessment tools in clinical practice. |
