March 2017 in “Journal of Cosmetic Dermatology” This meta-analysis suggests that local injection of platelet-rich plasma for androgenic alopecia is associated with an increased number of hairs and some increase in hair thickness, though larger studies are needed for confirmation.
This study reviewed two blinded randomized controlled trials and one prospective cohort study and found that PRP injections may increase hair density and induce hair regrowth in adults with androgenic alopecia and alopecia areata, with notably higher hair counts reported at specific follow-up intervals.
