ABSTRACT

Introduction: Alopecia areata is an inflammatory, immune and polygenic disease that causes hair loss without scarring, and thus affects mainly the scalp. No treatment has been shown to alter the course of the disease; very few are effective, so the autologous platelet concentrate is an available, safe and economical therapeutic alternative for hair survival and growth.
Objective: To assess the therapeutic effect of the autologous platelet concentrate in patients with alopecia areata.
Methods: A prospective, observational and descriptive longitudinal study was carried out with 34 patients from the protocolized alopecia consultation at Hermanos Ameijeiras Clinical-Surgical Hospital, to whom autologous platelet concentrate was applied every 21 days for three months.
Results: The multifocal clinical form predominated, accounting for 61.8% of the patients, together with the degree of severity of the S2 extension (26-50%) in 52.9%, respectively. Repopulation of hair in the alopecic plates was satisfactory. The autologous platelet concentrate was effective in 85.3% at the end of treatment and 14.7% had no response.
Conclusions: The autologous platelet concentrate was effective, being satisfactory in most of the patients at the end of treatment. Two to four months were necessary to achieve the outcome.
