Platelet-rich plasma (PRP) is an autologous preparation of plasma with concentrated platelets containing various growth factors and cytokines that enhance the body's inherent capacity to repair and regenerate hair follicles. A few studies and case reports support the use of PRP for the treatment of alopecia areata (AA). Further large-scale studies are needed to evaluate the efficacy of PRP as monotherapy or in association with other therapeutic modalities for AA. Although PRP is relatively safe and potentially effective, there is no standardized protocol or recommendations for the number of PRP sessions required to treat and maintain hair growth.
