    TLDR PRP therapy helps skin heal and improve by promoting cell growth and repair.
    Platelet-Rich Plasma (PRP) therapy in dermatology shows significant promise due to its regenerative effects and favorable safety profile. It is particularly effective in treating hair loss, promoting hair growth by enhancing angiogenesis, hair follicle cell proliferation, and prolonging the anagen phase. PRP also benefits skin conditions like melasma, vitiligo, and lichen sclerosus by reducing melanin synthesis, stimulating collagen production, and promoting melanocyte regeneration. The therapy's mechanisms include cellular proliferation, matrix formation, inflammation regulation, and tissue remodeling. While PRP's efficacy is well-supported, further randomized clinical trials are needed to fully understand and optimize its use in dermatology.

      Platelet-rich plasma (PRP) therapy for hair loss is expensive, painful, and often ineffective, with mixed reviews on its benefits. Alternatives like minoxidil, finasteride, and hair transplants are suggested as more reliable options.

      community Microneedling versus Platelet-Rich Plasma

      in Research/Science  10 upvotes 1 week ago
      Microneedling and Platelet-Rich Plasma (PRP) are equally effective for treating androgenetic alopecia, with no additional benefits from PRP over microneedling. Both treatments are safe and well-tolerated.

      community Why can't you drink caffeine after PRP?

      in Treatment  11 upvotes 3 years ago
      The conversation discusses avoiding caffeine after Platelet-Rich Plasma (PRP) treatment for hair loss because caffeine is a vasoconstrictor, which can reduce blood flow and hinder the healing process that PRP aims to promote.
