    Frontline, gold standard treatment for combatting androgenic alopecia

    Studysummary In this study, researchers developed and optimized ethanol-free microemulsion systems for transdermal finasteride delivery, finding that the predicted formulations closely matched their physical and chemical characteristics, potentially reducing adverse effects compared to oral administration.

    The study aimed to develop and optimize ethanol-free microemulsions (MEs) for the transdermal delivery of Finasteride (FN) to treat androgenic alopecia, minimizing systemic adverse effects. Using a hexagonal lattice design and Design Expert® software, the researchers formulated an FN-loaded ME with cinnamon oil, Tween®20, propylene glycol, and water. The optimal ME contained 11.58% cinnamon oil, 58.42% surfactant mixture, and 30% water. The physicochemical properties closely matched the predicted values, and scanning electron microscopy showed no significant damage to hair fibers treated with the ME. The study successfully predicted optimal ethanol-free ME systems for FN transdermal delivery.
