TLDR PRP therapy is promising for hair loss but needs standardized methods and personalization.
This literature review evaluates the use of autologous platelet-rich plasma (PRP) therapy for treating androgenetic alopecia (AGA), highlighting its popularity due to the regenerative potential of growth factors. The review synthesizes data from studies conducted between 2021 and 2024, examining the molecular targets of PRP growth factors, the standardization of preparation methods, and the clinical effectiveness of PRP, including meta-analyses and randomized studies. It emphasizes the role of PRP in combination treatments like hair transplantation and low-level laser therapy. The conclusion suggests that while PRP therapy is promising, safe, and effective, its full potential requires standardized protocols and a personalized approach that considers the biomolecular profile of the product and patient characteristics.
