Exosomes in Trichology: Current Applications and Future Perspectives in Alopecia Treatment

The study reviews the potential of exosomes in treating alopecia, noting their ability to stimulate hair growth, modulate inflammation, and regenerate hair follicles. Exosomes show promise in regenerative medicine for trichology by promoting dermal papilla cell proliferation and prolonging the anagen phase of the hair cycle. However, challenges such as the lack of standardized protocols, high costs, and limited long-term studies need to be addressed. Future directions include bioengineering exosomes for targeted therapy and integrating personalized medicine and AI for treatment precision. The study concludes that while exosomes are promising, their routine clinical use requires overcoming methodological and regulatory challenges through multicentric and randomized clinical trials.
