Hair loss trial pulled before it even started
NCT ID NCT02849470
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This trial aimed to test a combination of platelet-rich plasma and stem cells from fat tissue for treating male and female pattern hair loss. It was designed to compare different mixtures injected into the scalp. However, the study was withdrawn before enrolling any participants, so no results are available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Platelet-rich plasma and fat-derived stem cells
- What this could lead to
- If it had worked, this could point toward a regenerative treatment for hair loss using a person's own cells.
- What could go wrong
- The trial was withdrawn before enrolling anyone, so no data exists. Early-phase studies often fail to show benefit or have unexpected side effects.
