TLDR DPCP treatment improved hair regrowth and increased new capillaries in alopecia areata patients.
The study investigated the effects of diphenylcyclopropenone (DPCP) treatment on 20 patients with alopecia areata using videodermatoscopy and intravital videocapillaroscopy. Initially, patients exhibited typical alopecia areata features such as "exclamation point" hairs and "yellow dots." After 24 weeks of DPCP treatment, there was a significant reduction in these features and an increase in vellus hairs. Videocapillaroscopy showed a significant increase in new capillaries, indicating neoangiogenesis, which correlated with improved hair regrowth. The study concluded that DPCP therapy led to detectable neoangiogenesis, suggesting a compensatory mechanism for capillary loss in alopecia areata.
