Red Ultraviolet Hair Imaging and Hair Growth in Alopecia Areata

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective observational cohort study follows adults with limited plaque-type alopecia areata who are receiving intralesional corticosteroid injections as part of their usual care. Participants undergo baseline polarized trichoscopy and UV-trichoscopy, with follow-up imaging at weeks 4, 8, and 12 to track hair regrowth and changes in scalp findings. Red fluorescence intensity on standardized images is measured and analyzed for associations with treatment response and baseline trichoscopic features. The study does not alter treatment decisions; it only observes imaging biomarkers and their potential relationship to clinical outcomes. Imaging and analysis use standardized protocols to enable comparability across visits.
