Advances in Aesthetic Therapies: Platelet-Rich Plasma Procedure for the Treatment of Alopecia

The document provides information on the use of platelet-rich plasma (PRP) as a treatment for supporting hair growth and preventing hair loss. PRP works by regenerating tissue through growth factors that promote healing. Studies by Trink et al. (2013) and Alves and Grimalt (2016) concluded that PRP is effective in treating androgenetic alopecia. The treatment involves injecting PRP into the scalp, which triggers reparative responses, leading to neovascularization and the development of the epidermis and follicles. Response to PRP treatment can vary based on the patient's age, follicle distribution, and gender. Side effects may include headache and itching. Patients are advised to avoid certain activities and substances before and after the procedure, such as smoking and blood-thinning medication. The optimal initial treatment consists of a series of three treatments at 2-week intervals, with maintenance treatments recommended every 3-4 months. Patchy growth can result from inconsistent injection technique or variable follicle availability.
