A Comprehensive Literature Review: The Potential of Exosomes in Hair Growth and Transplantation

Exosomes, which are small extracellular vesicles, have shown promise in regenerative medicine for hair growth and dermatological applications. They contain bioactive molecules that regulate cellular processes and promote hair follicle regeneration. Derived from mesenchymal stem cells, exosomes enhance dermal papilla cell proliferation, modulate inflammation, oxidative stress, and promote angiogenesis, creating a favorable environment for hair growth. They are being explored for treating alopecia and scalp disorders due to their ability to modulate immune responses and aid tissue regeneration. While initial findings from PubMed and Cochrane are promising, more clinical studies are necessary to fully assess their safety and effectiveness in treating hair loss and improving skin health.
