What Are Exosomes?
Exosomes are microscopic vesicles derived from stem cells that deliver proteins, RNA, and growth factors to surrounding tissues. They function as messengers, promoting cell repair and regeneration. In dermatology, they are now being used to rejuvenate hair follicles damaged by DHT and inflammation.
How Exosomes Stimulate Hair Growth
When injected into the scalp, exosomes enhance cellular signaling, increase blood flow, and reactivate dormant follicles. A 2024 study in the International Journal of Trichology reported up to 25% greater regrowth when compared to PRP alone.
Procedure Details
The process involves microneedling followed by exosome application. Results are typically visible after 8–12 weeks, with minimal downtime. Sessions are recommended every 3–6 months for maintenance.
Benefits and Limitations
Exosome therapy is non-surgical and suitable for men and women. However, it remains costly, and standardization across providers is still evolving. Early adopters report thicker, shinier hair and improved scalp vitality.
Expert Takeaway
Dr. Emily Hartman notes, “Exosomes represent the next frontier of regenerative hair care. While still in early adoption, clinical data shows remarkable potential for non-hormonal regrowth.”
