April 2022 in “Pharmaceutics” This study reported that 5% minoxidil nanoparticles enhanced hair growth more effectively in mice than a commercial minoxidil solution, with significantly higher drug accumulation in the upper hair follicles.
28 citations
,
September 2019 in “International Journal of Nanomedicine” This study found that minoxidil nanoparticles increased drug delivery to hair follicles and improved hair growth more effectively in mice than conventional minoxidil formulations.
10 citations
,
January 2014 in “Chemical and Pharmaceutical Bulletin” This study found that hair follicle-plugging reduced skin permeation of certain model drugs, with effects varying based on EtOH pretreatment and the drug being evaluated.
263 citations
,
February 2011 in “Journal of Controlled Release” This study found that medium-sized particles (643 and 646 nm) penetrated deeper into porcine hair follicles in vitro than smaller or larger particles, suggesting size-selective targeting within follicular sites.
2 citations
,
January 2009 in “Folia Pharmacologica Japonica” This review covers potential molecular targets for androgenetic alopecia treatments but presents no new experimental findings; the authors highlight various in vitro and in vivo screening methods for therapeutic compounds.
323 citations
,
April 2006 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that 40 nm nanoparticles can effectively penetrate into hair follicles and epidermal Langerhans cells in human skin samples, potentially enabling efficient transcutaneous vaccine delivery.
316 citations
,
June 2004 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.
25 citations
,
January 2002 in “Folia Pharmacologica Japonica” This article reviews the proposed mechanism of minoxidil in treating androgenetic alopecia, suggesting it may prolong the anagen phase by modulating cell growth factors and vascular activity, but reports no new results.
