    Development of Ethosomes for the Topical Treatment of Androgenic Alopecia: Ethanol Effect on Dutasteride Targeting to the Hair Follicles

    June 2025 in “ Pharmaceutics
    Jayanaraian F. M. Andrade, Rafael V. Rocho, Breno N. Matos … Taís Gratieri
    Studysummary This study found that ethosomes containing 30% ethanol slightly improved the targeting of dutasteride to hair follicles in vitro, with a higher targeting factor compared to dried ethosomes and controls after 24 hours on porcine skin.
