May 2017 in “Journal of Cosmetic Dermatology” PRP injections improve hair density and thickness in women with hair loss.
January 2026 in “Journal of Advanced Trends in Medical Research” The review compares exosome therapy and platelet-rich plasma (PRP) for hair loss treatment, highlighting exosomes' potential in regenerative dermatology. Exosomes, particularly from mesenchymal stem cells and dermal papilla cells, show promise in enhancing hair density and transitioning hair phases, with a study of 30 male patients with androgenetic alopecia showing increased hair density. Exosomes may also benefit chemotherapy-induced alopecia and trichorrhexis nodosa. PRP, derived from a patient's blood, has a longer clinical history and is effective in treating various alopecia types, including androgenetic alopecia and alopecia areata, by increasing hair density and stimulating follicular regeneration. Both therapies face challenges like standardization and regulatory issues, and further research is needed to confirm long-term efficacy and establish treatment protocols.
