January 2017 in “Hair therapy & transplantation” This study found that using a topical zinc-thymulin spray on the scalp for more than 6 months was safe and significantly improved hair growth in adults with male pattern baldness, with notable increases in certain hair types and no reported adverse effects.
In this study, researchers developed a novel gel formulation combining zinc oxide nanoparticles and finasteride-loaded nanostructured lipid carriers, which showed promising results for topical delivery and effective skin penetration, potentially offering a new treatment approach for androgenic alopecia.
February 2024 in “International journal of pharmaceutical sciences and nanotechnology” In this article, researchers explored the potential of lipidic nanocarriers to enhance the delivery and effectiveness of finasteride in a topical gel form for androgenic alopecia, aiming to improve treatment options and reduce systemic adverse effects.
December 2015 in “Dermatologic Therapy” This article compares the efficacy of topical tea and zinc sulfate in treating acne rosacea but does not present new clinical results.
In this study, formulations containing 20% zinc oxide nanoparticles demonstrated stability and improved spreadability without penetrating the deepest skin layers, instead accumulating in skin furrows and hair follicles.
