Promises And Pitfalls Of Regenerative Therapies For Androgenetic Alopecia: Platelet-Rich Plasma, Photobiomodulation, Stem Cells, And Exosomes

This study critically reviewed recent evidence (2020–2025) on treatments like platelet-rich plasma, photobiomodulation, stem cells, and exosomes for androgenetic alopecia, finding emerging but limited efficacy data and emphasizing the need for standardized protocols to enhance transparency and patient safety.

This review suggests that mesenchymal stem cells and exosomes may be effective in regenerating hair follicles for treating androgenic alopecia, but more research on their mechanisms and efficacy is necessary.

This paper describes various emerging regenerative therapies for hair loss, such as platelet-rich plasma, exosomes, and low-level laser therapy, but it doesn't provide results or conclusions about their efficacy.

This review explores the evidence for platelet-rich plasma, exosomes, and other regenerative therapies as adjuncts in hair transplantation, finding that PRP has the most support, but highlights the need for standardization and transplantation-specific studies.

This systematic literature review found that exosome and PRP therapies show promise as effective, minimally invasive options for treating androgenetic alopecia, with clinical benefits potentially superior to or complementary to minoxidil, although standardization and larger clinical trials are needed to confirm long-term safety and efficacy.
