    TLDR Platelet-rich plasma (PRP) can help restore hair, but the best method for preparing and using it is still unclear.
    The document reviews the therapeutic role of Platelet-rich plasma (PRP) in hair restoration. PRP is an autologous substance created from the centrifugation of patients' own blood, and it has gained popularity as a minimally invasive hair restoration technique. The review includes 56 unique original studies with 2,114 unique patients. The studies show that PRP has a therapeutic role in hair restoration, with multiple treatments at 4-week intervals being recommended. Most studies used an activator and found some benefit to double-centrifugation. However, there is still a significant gap in knowledge regarding a defined, evidence-based, and standardized preparation technique for PRP use in hair restoration. All of the included studies called for the need for further rigorous, randomized double-blinded trials assessing PRP and hair restoration.

      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.

      Before getting a hair transplant, it's crucial to research and understand that ongoing treatments like finasteride, dutasteride, or minoxidil are necessary to maintain results. Concerns were raised about Turkish clinics, including overharvesting grafts, lack of regulations, and discouraging finasteride use.

      community Do Platelet-rich plasma, PRP work?

      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.
