June 2026 in “Journal of Cosmetic Dermatology” This study explores the use of microneedle-assisted delivery of PEGylated recombinant human fusion collagen (PEG-rhCol-F) for treating androgenetic alopecia (AGA). In a testosterone-induced AGA mouse model, the treatment significantly promoted hair regrowth, increased hair follicle count, and facilitated the transition to the anagen phase, linked to the activation of the Wnt/β-catenin-VEGF axis. A subsequent three-month pilot clinical trial with 15 AGA patients showed marked improvements in hair density and diameter, with a shift from vellus to terminal hairs. The treatment was well-tolerated, with only mild, transient adverse reactions. The study suggests that this dual-mechanism approach, combining ECM repair and functional pathway activation, is promising for AGA treatment and warrants further clinical investigation.
