    TLDR Platelet-rich plasma and stem cell therapies are accepted treatments for hair restoration, with specific protocols recommended for best results, but more standardization is needed in stem cell use.
    The commentary from 2020 discussed the use of platelet-rich plasma (PRP) and stem cell therapy for hair restoration. Initially, these treatments were considered questionable, but controlled clinical studies and basic research have led to their acceptance as treatment protocols. The paper highlighted the importance of creating PRP preparations with 3 to 5 times the normal platelet concentration and suggested at least 3 sessions a month apart with follow-up sessions at a later date. It was noted that there is relapse after PRP injections in treatments that extend beyond 12 months, supporting the use of follow-up injections. The commentary also discussed the potential of stem cells in hair restoration, but noted that the data did not provide the same level of evidence as for PRP due to lack of standardization in stem cell harvesting and application. The authors recommended a specific treatment protocol for PRP with 3 monthly injections followed by a fourth within at least 6 months after the initial series, as well as maintenance injections at 12 to 18 months.

      in Progress Pictures  26 upvotes 11 months ago
      A user shared their 1.5-year hair restoration journey, successfully using mesenchymal stem cell therapy, Platelet Rich Plasma (PRP) injections, and a topical compound of finasteride and minoxidil, avoiding a hair transplant and oral finasteride. They experienced significant hair regrowth, particularly crediting the stem cell therapy for quick initial results.

      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.

      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.
