Fawzy MM, Hay RA, Mohammed FN, et al. - Given that both platelet‐rich plasma (PRP) and intralesional corticosteroids (ILCs) are significant treatment modalities of patchy alopecia areata (AA), researchers sought to analyze trichoscopic diagnosis of AA and monitoring the treatment response to PRP vs ILCs in patchy AA treatment. Thirty-one patients with patchy AA were divided into two groups: (group A) received ILCs whereas (group B) received PRP once monthly for 3 months. In terms of the number of follicular units per opening, black dots, broken hairs, and dystrophic changes, there was a significant improvement in trichoscopic findings in both groups. According to this comparative study, trichoscopy may assist with the diagnosis, evaluation of the effectiveness and safety of both modalities and may give a clue for treatment response. Both ILCs and PRP in patchy AA treatment were effective.
