ABSTRACT

Background: Alopecia areata (AA) is a chronic non-scarring alopecia that involves the scalp and/or body, and is characterized by patchy areas of hair loss without any signs of clinical inflammation. Various therapies have been proposed for their treatment.But none have been shown to alter the course of the disease. Platelet Rich Plasma (PRP) is a volume of autologous plasma that has a high platelet concentration. Growth factors released from platelets may act on stem cells in the bulge area of the follicles, stimulating the development of new follicles and promoting neovascularization. Aim: To evaluate and compare the efficacy of intralesional injection of autologous platelet rich plasma with intralesional injection of triamcinolone acetonide (10mg/ml) in the treatment of alopecia areata. Methodology: 74 patients with alopecia areata were allocated into 2 groups and treated with triamcinolone and PRP injections. Treatment outcome was measured by taking into account extent and density of regrowth of hair and was expressed as a percentage of overall growth. Results: Forty eight patients were treated with triamcinolone injections and 26 patients were treated with PRP injections. Patients treated with PRP had an earlier response at the end of 6weeks than patients treated with triamcinolone. However, this difference was statistically insignificant. The overall improvement at the end of 9 weeks was 100% for all patients in both groups. Conclusion:  PRP is a safe, simple, biocompatible and effective procedure for the treatment of alopecia areata with efficacy comparable with triamcinolone.
