TLDR PRP can help treat hair loss but needs standardized methods for best results.

The document reviewed the use of platelet-rich plasma (PRP) in treating androgenetic alopecia (AGA), highlighting its potential to stimulate hair growth through various pathways. Despite promising results, the effectiveness of PRP was limited by inconsistent preparation methods and lack of standardization. Meta-analyses of randomized controlled trials (RCTs) showed an increase in hair diameter and count, but results were not statistically significant due to high methodological variability. The manual double-spin method was recommended for PRP preparation, with a platelet concentration of 1 to 1.5 million/μL being optimal. PRP showed better hair growth results compared to finasteride, minoxidil, and low-level laser therapy, and was effective in women unresponsive to minoxidil. The study concluded that PRP should be part of a multipronged approach for treating AGA due to its minimal adverse effects and significant efficacy.
