NCT ID NCT04018859
First seen Jul 01, 2026 · Last updated Jul 02, 2026 · Updated 1 time
Summary
This study investigates whether injecting platelet-rich plasma (PRP) from a person's own blood can improve mild to moderate eyebrow thinning. Participants receive either PRP or saline injections into the eyebrows, and changes are tracked through photographs over nine months. The trial is a small pilot study to see if this approach is feasible and worth further research.
