August 2022 in “Journal of Controlled Release” In this study, a microneedle patch containing conditioned media from hypoxia-pretreated stem cells enhanced hair regeneration in an androgenetic alopecia mouse model by boosting perifollicular vascularization and hair follicle stem cell activation compared to minoxidil.

February 2001 in “Journal of Clinical Investigation” This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

March 2019 in “Experimental Dermatology” This review discusses the role of perifollicular macrophages in hair growth and suggests targeting them could be relevant for managing hair growth disorders, but reports no new results.
May 2026 in “Stem Cell Research & Therapy” This study found that exosomes derived from dental pulp mesenchymal stem cells (DPSC-Exos) significantly promoted hair regrowth and follicle density in a mouse model of androgenetic alopecia, showing similar efficacy to minoxidil by activating pathways that improve follicular vascularization and dermal papilla cell function.
September 2024 in “Journal of Ethnopharmacology” In this study, Terminalia bellirica extracts promoted hair regrowth in testosterone-induced AGA mice, possibly by inhibiting type II 5α-reductase activity and enhancing the MAPK signaling pathway.
