Could a scalp gel save your hair during chemo? early trial begins
NCT ID NCT07033845
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial tests a topical phenylephrine gel applied daily to the scalp for three weeks. Researchers want to see how much of the drug enters the bloodstream and whether it is safe. The study involves 24 healthy women aged 18-55, not cancer patients, so it is a first step toward possibly preventing chemotherapy-induced hair loss.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Phenylephrine (topical solution applied to scalp)
- What this could lead to
- If it works, this could point toward a way to reduce hair loss during chemotherapy.
- What could go wrong
- This is a very early, small study in healthy women, not patients. It only checks safety and absorption, not whether it actually prevents hair loss. Side effects like skin irritation or blood pressure changes are possible.
