Korean exosome research on hair loss
Where the evidence stands and its limits
Quick answer
Korean studies examine stem-cell exosomes for stimulating the hair cycle. Small trials report increased hair density when combined with microneedling, but large long-term studies are still lacking.
Key facts
- Evidence level
- Small-scale studies
- Combined with
- Microneedling, standard drugs
The proposed mechanism is that exosomes deliver cell-signalling cargo that pushes dermal papilla cells back into the growth phase.
For androgenetic hair loss, standard medication remains first-line; exosomes should be viewed as adjunctive rather than a replacement.
Frequently asked questions
