October 2023 in “Current Issues in Molecular Biology” In this study, researchers observed that the YH complex, made from Astragalus membranaceus and Cinnamomum cassia, promoted hair regrowth and increased hair shaft thickness in mice, potentially through increased growth factors and Wnt/β-catenin signaling, suggesting its use for treating various forms of hair loss.
February 2026 in “International Journal of Molecular Sciences” This study found that 3-hydroxypropionic acid improved the function of hair follicle cells under oxidative stress, suggesting potential as a treatment for stress-related hair loss.
January 2026 in “Scientific Reports” In this study, researchers found that sesamin, a component of sesamum, modulated the AR-MAPK-Wnt signaling pathway in DHT-stimulated HaCaT keratinocytes, demonstrating potential multi-target activity against molecular events in androgenetic alopecia.
February 2025 in “BMC Veterinary Research” This study examined proteomic changes in Inner Mongolia cashmere goat skin, finding 631 proteins differentially regulated during hair growth stages; key keratin proteins, crucial for hair follicle development, were localized in secondary hair follicles.
April 2026 in “Journal of the Korean Society of Cosmetology” This study found that Limosilactobacillus reuteri NCHBL-005, derived from honeybees, may promote hair growth via a novel non-androgenic mechanism involving the Wnt/β-catenin signaling pathway, as it increased hair follicle size and number in mice and influenced related gene expression in human follicle cells.
