    TLDR Platelet Rich Plasma-Derived Extracellular Vesicles show promise for healing and regeneration but need standardized methods for consistent results.
    The systematic-narrative review analyzed 20 studies on the use of Platelet Rich Plasma-Derived Extracellular Vesicles (PRP-EVs) in regenerative medicine. PRP-EVs have shown potential in various fields including osteoarthritis, tissue regeneration, diabetic retinopathy, intervertebral disc degeneration, muscle injury, wound healing, hair loss, osteonecrosis, and dental pulp or cartilage regeneration. They have been found to promote cell proliferation, migration, and various healing processes. In the field of hair growth, PRP-EVs have shown potential in enhancing the inductivity of hair dermal papilla cells. However, the lack of standardization in PRP and EV procedures makes it challenging to compare results across studies. The review calls for establishing standardized conditions to ensure optimized and detailed protocols and define parameters such as the dose or the EV origin. Further studies are also needed to understand the real contribution of EVs to PRP in terms of composition and functionality.

      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.

      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.
