    TLDR PRP therapy increases hair density for androgenetic alopecia.
    This document discusses the use of platelet-rich plasma (PRP) as a treatment for androgenetic alopecia (AGA). A meta-analysis of 10 studies found that PRP therapy resulted in a significantly greater increase in hair density compared to baseline counts and placebo. The authors recommend three sessions of PRP at 1-month intervals followed by a maintenance regimen, subdermal injection depth, and the use of sonication and microparticles. While there is evidence to support the use of PRP for AGA, more research is needed to determine the optimal protocol for treatment and to establish its long-term safety and efficacy.
