    TLDR PRP treatment increases hair density and thickness in androgenetic alopecia by 79%.
    A systematic review and meta-analysis of 30 studies with 687 patients found that platelet-rich plasma (PRP) treatment is effective in increasing hair density and thickness in men and women with androgenetic alopecia (AGA), resulting in a 79% increase in hair coverage. PRP treatment lacks serious adverse effects and is a low-risk, low-cost autologous product. However, the quality of evidence is limited due to the heterogeneity of the studies included in the analysis, and future research should focus on optimizing treatment protocols and investigating variability amongst studies.
