    TLDR Platelet-rich plasma may improve healing and hair growth in cosmetic surgery but results vary.
    The 2013 document reviews the use of platelet-rich plasma (PRP) in cosmetic surgery, emphasizing its role in enhancing wound healing and its potential in esthetic procedures like hair restoration and soft tissue augmentation. PRP, which is plasma with higher levels of platelets and growth factors, is believed to aid in tissue regeneration through the release of growth factors such as PDGF, TGF-ß, and VEGF. These factors contribute to cell differentiation, proliferation, collagen synthesis, and angiogenesis. The document highlights PRP's clinical applications in skin rejuvenation, recovery time reduction in procedures like CO₂ laser resurfacing, and improved soft tissue healing. It also notes PRP's promise in hair restoration, where it may stimulate hair regrowth and increase hair thickness. PRP is prepared by centrifugation of whole blood and activation of platelets. Despite the potential benefits, the document cautions about the variability in clinical outcomes and suggests that future positive study results could establish PRP as a standard in cosmetic surgery. Two FDA-approved systems for PRP preparation mentioned are Selphyl and RegenKit.

      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.

      A 20-year-old has been using finasteride for 2 years and switched from 5% to 10% minoxidil, causing issues. The doctor now prescribes 5% minoxidil twice daily, dutasteride on alternate days, and 3 PRP sessions for hair regrowth.

      community Do Platelet-rich plasma, PRP work?

      in Research/Science  13 upvotes 1 year ago
      Someone's brother tried Platelet-rich plasma (PRP) for hair loss; it had minimal effect on hair but improved skin appearance. Microneedling at home was suggested as a more sustainable alternative.
