New scalp treatment for hair loss under study
NCT ID NCT07402330
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tests a drug called DA-020 in 60 healthy women aged 18-55. The goal is to measure how much of the drug enters the blood after one application to the scalp and to check for side effects like blood pressure changes. This research helps understand the drug's safety before testing it in people with hair loss from chemotherapy.
