    TLDR Platelet-Rich Plasma (PRP), a substance from a patient's own blood, can stimulate hair regrowth in people with Androgenetic Alopecia (AGA) who haven't had success with other treatments, but more research is needed to optimize its use.
    The document from 3 years ago discussed the use of Platelet-Rich Plasma (PRP), a growth factor concentrate from a patient's own blood, for hair restoration in patients with Androgenetic Alopecia (AGA) who had not found success with other treatments. PRP was injected into areas of hair loss, stimulating hair regrowth, possibly by promoting the development of new hair follicles and neovascularization. Out of 24 studies, 21 reported positive outcomes with PRP. However, the document emphasized the need for further research to optimize PRP preparation and administration procedures, identify the most beneficial patient populations, and conduct long-term follow-up of objective hair loss outcomes.
