    TLDR Platelet-rich treatments can help improve wound healing and tissue repair.
    The document reviews the multifaceted role of platelets in hemostasis, tissue repair, and immune response, and the use of platelet-rich concentrates for therapeutic purposes in clinical settings. It explains that platelets release mediators that coordinate tissue repair and that local application of platelet-rich concentrates and fibrin can enhance wound healing in medicine and dentistry. The review details the preparation methods for platelet-rich plasma (PRP) and platelet-rich fibrin (PRF), which involve centrifugation of blood, with or without anticoagulants, to concentrate platelets. The document acknowledges the potential of PRP and PRF in treating various conditions, including alopecia and skin rejuvenation, but also notes the current limitations due to small study sizes and potential bias, highlighting the need for more standardized and well-designed studies. The authors, E.E.J. and M.H., with contributions from A.B. and P.J., report no external funding or conflicts of interest.

      The conversation is about hair loss treatments, focusing on minoxidil and finasteride, with suggestions for microneedling and dermarolling to improve hair thickness. The original poster has used minoxidil for four years and finasteride for over a year but is exploring additional options for better results.

      community I have been on finasteride for 9 months. (6 months on 0.25 mg, 3 months into 0.5 mg daily) here are the progress pictures.

      A user shared progress pictures after 9 months on finasteride, starting with 0.25 mg and increasing to 0.5 mg daily, noting improved hair density, especially at the crown, with initial side effects that resolved after the first month. The discussion includes user experiences with finasteride, concerns about side effects, and alternative treatments like rosemary oil and platelet-rich plasma therapy.

      community Thoughts on platelet-rich plasma therapy

      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.
