Pharmaceris H-Stimutone is a specialized double-action shampoo designed to prevent premature graying while stimulating hair growth. It's formulated for men and women experiencing hair loss and premature graying, working to restore natural hair color and strengthen hair follicles. The shampoo contains key active ingredients including natural growth factor FGF, caffeine complex, nut extract, naringenin and D-panthenol. It works by activating mitochondria to extend cell life and restore natural pigmentation while strengthening hair follicles. For best results, it should be used at least 3 times per week. The formula is dermatologically tested and suitable for sensitive scalps. The shampoo gradually darkens gray hair with regular use but does not have an immediate dyeing effect.
