New pill could help women regrow hair – but It's not a cure
NCT ID NCT07146022
First seen Jun 27, 2026 · Last updated Aug 18, 2026 · Updated 2 times
Summary
This study tests an oral drug called VDPHL01 in 552 women aged 18–65 with mild to moderate hereditary hair loss. Participants take a pill once or twice daily for about 13 months. The goal is to see if it increases hair count and if women feel their hair looks better. It's a placebo-controlled, double-blind trial, meaning neither participants nor doctors know who gets the real drug.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- VDPHL01 (an oral tablet)
- What this could lead to
- If it works, this could provide a new daily pill to help women with hereditary hair loss regrow hair and feel better about their appearance.
- What could go wrong
- This is a Phase 3 trial, but it's still experimental. The drug may not work better than placebo, and side effects are possible. Results are based on hair counts and self-assessment, not a cure.
