Hair Loss & Restoration: cell-therapy evidence by therapy class
Across every stem-cell intervention, ClinicalTrials.gov holds 17 registered records for Hair Loss & Restoration — 5 recruiting, 2 at Phase 3 or 4, in 6 countries. Snapshot 2026-08-29.
The condition, and why cells are proposed
Androgenetic alopecia is a hormone-driven miniaturisation of follicles, not follicle death, which is why regenerative approaches are biologically plausible: the target still exists. It is also the one tracked indication where exosome registrations outnumber whole-cell studies, reflecting how quickly aesthetic markets adopt cell-free products.
Therapy classes side by side
Counts come from separate registry queries per class; a study testing two interventions can appear in more than one row, so rows do not sum to the all-interventions total.
Geography of the research
United States accounts for about 27% of country mentions among sampled studies; 6 countries host at least one site.
| Country | Studies with a site there |

The largest registered studies
Sorted by planned enrolment — size is not quality, but a 300-participant trial can answer questions a 12-participant series cannot.

Reading this honestly
These figures describe effort, not outcome. Published results, with their control arms and endpoints, are where benefit is decided. For Hair Loss & Restoration specifically, the practical question is which registered study — if any — matches the product a provider is offering, and what its outcome measures actually are.
Frequently asked
How many stem-cell trials exist for Hair Loss & Restoration?
17 registered records mention a stem-cell intervention for this condition (2026-08-29 snapshot), of which 5 were recruiting.
Which therapy class is furthest along for Hair Loss & Restoration?
Ranked by Phase 3/4 records: PRP (3), exosomes (1), MSC (0), HSCT (0).
Does a recruiting trial mean I can be treated?
No. Trials have eligibility criteria, and joining one is not the same as buying a treatment. Paying a clinic for an unproven intervention outside a registered study gives you neither the protections nor the data collection of a trial.
