Background: Alopecia Areata (AA) is an autoimmune disease that targets hair follicles and is driven by T cells specific to that organ. As it was found that the lack of expression of VDRs is associated with reduced hair follicle growth and epidermal differentiation. The aim of this study was to evaluate the efficacy and safety of intralesional vitamin D and to assess it by the dermoscope. Patients & Methods: This study clinical trial included a total of 20 patients with alopecia areata, who received intralesional injection of vitamin D (an aqueous preparation of cholecalciferol (Devarol ampule 200000iu/2ml, Memphis, Egypt) (2.5mg/ml) the maximum total amount of Vitamin D3 injected in every session was 1.25mg (0.5ml).
