April 2024 in “Bioactive materials” This study found that a microneedle system delivering VEGF and Ritlecitinib improved hair regeneration in mice with androgenetic alopecia, showing faster anagen onset and better hair quality compared to minoxidil.
October 2023 in “Bioactive Materials” This study developed a novel liposome-based delivery system for Minoxidil and nitric oxide, which showed promising results in promoting hair regrowth in an androgenetic alopecia model by enhancing transdermal absorption, prolonging skin retention, and reducing inflammation.

December 2022 in “Bioactive Materials” In this study, researchers developed a nanocomposite microneedle patch containing copper/zinc dual-doped silica nanoparticles, which release substances to promote hair follicle regeneration by targeting various pathophysiological aspects of androgenic alopecia, presenting an effective anti-hair loss treatment strategy.

October 2022 in “Regenerative Therapy” This review discusses regenerative medicine approaches for treating alopecia, including mesenchymal stem cell therapies and platelet-rich plasma, but reports no new clinical results, emphasizing the need for further study.
2 citations

May 2022 in “Advanced therapeutics” This study reported that a novel vasodilator drug called TOP-M119, when delivered using a specially designed dissolving microneedle system, showed enhanced targeting of hair follicles and effectiveness in treating alopecia, demonstrated through in vitro, ex vivo, and in vivo studies involving mouse skin.

January 2022 in “Journal of Investigative Dermatology” This study found that androgen receptor signaling is linked to blood vessel regression in the dermal papilla of balding scalp, contributing to hair follicle miniaturization in androgenetic alopecia.
23 citations
,
January 2021 in “Biomedicine & Pharmacotherapy” This study found that dihydrotestosterone induced hair loss and changes in hair morphology in male C57BL/6 mice, effects that could be partially reversed by the AR antagonist bicalutamide.
30 citations
,
January 2019 in “International Journal of Trichology” This study observed that androgenetic alopecia significantly impacts the quality of life in males, with personal relationships being notably affected, based on Dermatology Life Quality Index and hair-specific Skindex-29 assessments.

September 2011 in “Journal of Investigative Dermatology” IL-6 contributes to hair loss by shortening the growth phase and causing hair follicles to regress.
11 citations

May 2009 in “Medical Hypotheses” This paper proposes a theory explaining how the normal anabolic effects of androgens lead to structural changes and hair follicle miniaturization, contributing to androgenic alopecia.
