    TLDR Platelet-rich plasma shows potential for hair growth, but more research is needed to determine the best preparation method.
    The 2019 study "Platelet-rich Plasma for Hair Growth" explored the potential of platelet-rich plasma (PRP) in hair restoration, particularly for androgenetic alopecia (AGA), alopecia areata (AA), and telogen effluvium. The authors found that PRP, a concentration of platelets in plasma with growth factors, showed promise in stimulating hair regeneration. However, due to a lack of standardization in PRP preparation, it was challenging to compare results and determine its clinical efficacy. The study highlighted the need for further randomized placebo-controlled studies with larger sample sizes to better understand PRP's effects on hair regrowth in AGA. The optimal PRP preparation for AGA remained undetermined and required further investigation.

      Scalp biopsies are crucial for diagnosing hair loss conditions like Diffuse Unpatterned Alopecia (DUPA) and retrograde hair loss, as treatments like finasteride and dutasteride may not be effective if other conditions are present. Combining PPAR-GAMMA agonists with retinoids could improve treatments for conditions like Lichen Planopilaris.

      Key treatments for hair preservation include minoxidil, finasteride/dutasteride, and microneedling, with additional options like specific shampoos, oils, biotin, zinc, tretinoin, clascoterone, and low-level laser therapy. Maintaining a healthy lifestyle, reducing stress, and addressing nutrient deficiencies can also support hair health.

      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.
