TLDR PRP shows promise for treating hair loss but needs more research.

This literature review evaluates the effectiveness of Platelet-Rich Plasma (PRP) in treating androgenetic alopecia (AGA), a condition affecting over 60% of the global population and responsible for more than 90% of hair loss disorders. The review analyzed 27 controlled studies and clinical trials from 2012 to 2022, involving over 1,072 subjects who received PRP or control treatments bi-monthly to monthly for 3-6 months. The majority of these studies reported positive outcomes, including increased hair growth, density, diameter, and quantity. However, further research is needed to standardize PRP protocols and explore its potential as a combination therapy for optimal AGA treatment.
