Can stem cell exosomes regrow hair? new trial investigates
NCT ID NCT07693244
First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time
Summary
This trial tests whether injections of human umbilical cord stem cell exosomes can regrow hair in men with male pattern baldness. Participants receive either the exosome treatment or a placebo injection into the scalp every four weeks for three sessions. The study measures changes in hair density and thickness over 24 weeks to see if the treatment outperforms placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- human umbilical cord mesenchymal stem cell-derived exosomes
- What this could lead to
- If it works, this could offer a new, non-surgical treatment for male pattern baldness that stimulates hair regrowth.
- What could go wrong
- This is a Phase 2 trial with 120 participants, so results are still early. The treatment may not work better than placebo, and risks from scalp injections include pain, swelling, or infection.
