Minoxidil shows promise for reversing gray hair in new study

NCT ID NCT06813963

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed Phase 4 trial tested whether applying minoxidil (5%) to the scalp twice daily for 12 months could restore color to gray hair in adults aged 18 to 65 with non-medical graying. Researchers compared 141 participants using minoxidil versus a placebo, measuring changes in a gray hair severity scale. The goal was to see if this common hair-loss drug could also repigment hair, offering a potential alternative to dyes.
