This study reports that biomass activated carbon fibers derived from metaplexis japonica seed hair effectively adsorb methyleneblue dye, demonstrating high capacity and rapid adsorption performance.
This study observed that methyleneblue, a mitochondrial-targeted antioxidant, promotes hair follicle stem cell proliferation and viability through reduced oxidative stress and enhanced β-catenin signaling, and it may also protect against hair loss related to glucagon-like peptide-1 receptor agonists by reducing metabolic stress.
Follicium XR™ is a topical treatment for hair loss containing RU58841, AHK-Cu, GHK-Cu Peptide, caffeine, D-Biotin, methyleneblue, keratin, and spermidine. RU58841 is considered the most effective ingredient, but concerns exist about its stability in water.
