    TLDR PRP injections did not significantly improve hair growth.
    The randomized, placebo-controlled pilot study investigated the efficacy of platelet-rich plasma (PRP) injections for treating androgenetic alopecia in 30 healthy male subjects. Over the course of the study, 20 subjects received PRP treatments while 10 received saline injections. The efficacy was measured using the TrichoScan system to assess changes in hair number and diameter, and clinical improvement was evaluated by an independent reviewer using patient photographs and a 5-point Likert scale. Subject satisfaction was also surveyed. The study concluded that PRP as a monotherapy did not result in any significant improvements in hair growth, as measured by both TrichoScan and visual assessments.

      The review discusses traditional hair loss treatments like minoxidil and finasteride, and newer options like Low-Level Laser Therapy, microneedling, and platelet-rich plasma for androgenetic alopecia. It highlights the need for more high-quality trials to assess these treatments' effectiveness and standardized protocols for emerging therapies.
