January 2006 in “International Journal of Cosmetic Science” This study investigated the penetration of a low-molecular-weight cationic conditioning compound into the hair cortex and suggests it may improve hair's fatigue resistance.
August 2019 in “RIUnB Institutional Repository (University of Brasília)” This study developed polymer nanoparticles with and without chitosan coating to deliver dutasteride to hair follicles for treating androgenic alopecia. Both nanoparticle types showed controlled drug release and enhanced follicle targeting, especially with mechanical stimulus, supporting their potential as effective topical carriers in skin layers.
