I know unkempt, messy, brassy looking hair can make you look older but hair itself looking older? That boggles my brain! I mean it seems pretty logical but I honestly can’t say I have given it much thought. The shampoo and conditioner duo promises to fight the 7 signs of “aging” hair - “unruly grays, dryness, lackluster color, thinning, breakage, split ends, and frizz” when using it. After using the duro for three uses, I feel like my hair was douse in anti-aging cream. I have this one really gray hair that sticks up in the middle of my forehead no matter what I do. I noticed after using the duo, this doesn’t occur anymore. My hair felt smooth, soft and I noticed I could go almost 3 to 4 days without having to wash my hair because it was oily!
