Supplements Can Help With The Health of Color_Treated Hair : Vitamins are another key to keeping color_treated hair healthy and shiny. Vitamin C keeps blood vessels in the scalp healthy by supporting hair follicles. Vitamin C also helps you absorb iron from plant proteins.

Buy two boxes. If your hair is past your shoulders, or shoulder length and extremely coarse, use two boxes of the same shade to ensure full coverage. Just make sure to mix the dyes in a glass or plastic bowl a metal one will oxidize the dye and cause it to change color. Consider your hair texture : Hair texture matters just as much when dyeing your hair as it does when cutting it. "Coarse, curly, frizzy, or unruly hair sucks up color faster and will become cooler_toned when you dye it, so it will look ashier, or slightly bluish," says Ionato. "Fine to medium hair textures don't absorb color as easily and will become a slightly warmer tone when you add dye, meaning it will have orange, red, or copper undertones." So what does that mean for you when you're standing in the aisle at the drugstore? If your hair is frizzy or curly, pick a color that's warm (golden, copper, bronze), but a little lighter than your natural hair color; if your hair is fine and straight, choose cooler shades (champagne, beige) that are slightly darker than your natural color.
