TLDR PRP and LLLT can improve hair growth in AGA, but more research needed.

This document discusses the use of platelet-rich plasma (PRP) and low-level laser therapy (LLLT) as treatments for androgenetic alopecia (AGA), a common form of hair loss. PRP injections have shown some positive results in improving hair growth parameters, but the efficacy may vary by gender and preparation modality. LLLT devices emit red or near-infrared laser light, which has been shown to have tissue repair properties. Clinical studies have found that LLLT can improve hair density and hair count in both men and women with AGA. However, more research is needed to fully understand the mechanisms behind LLLT and to determine the optimal treatment parameters for different types of AGA.
