April 2025 in “OPAL (Open@LaTrobe) (La Trobe University)” This study developed a dissolvable microneedle system loaded with nanozymes and minoxidil that enhanced hair regeneration in androgenetic alopecia mouse models by improving blood flow, reducing reactive oxygen species, and increasing cell proliferation compared to minoxidil alone.
April 2026 in “ACS Applied Materials & Interfaces” In this study, researchers developed a probiotic-based microneedle system combining Weissella cibaria and clascoterone to target androgenetic alopecia, which in a mouse model improved hair density, vascular regeneration, and reduced inflammation, suggesting a promising treatment approach.
April 2025 in “ACS Applied Nano Materials” In AGA mouse models, this study found that the combination of nickel–copper nanozymes and minoxidil in dissolvable microneedles significantly enhanced hair regeneration and improved the hair follicle microenvironment by reducing reactive oxygen species and increasing vascular density, compared to minoxidil alone.
March 2024 in “ACS Applied Materials & Interfaces” This study developed a delivery platform using hyaluronic acid-based dissolvable microneedles with nanoliposomes containing kopexil and kopyrrol, which showed improved hair regeneration for treating androgenetic alopecia in vivo at lower dosages compared to minoxidil.
August 2026 in “Journal of Nanobiotechnology” In testosterone-induced AGA mouse models, this study found that a dual-drug-loaded cationic nanoemulsion of minoxidil and finasteride enhanced follicle-associated retention, supporting hair regeneration while reducing systemic absorption and showing good skin compatibility, indicating a promising approach for androgenetic alopecia treatment.
