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 However, the study was withdrawn before enrolling any participants, so no results are available.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The trial was withdrawn before enrolling anyone, so no data exists.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.
