A surprising number of testers revealed a dirty secret: stripping down when coloring to avoid staining clothes. If that's not your style, wear an old button_front shirt or robe that way, you won't have to lift anything over your head when it's time to rinse. You can also lay down garbage bags instead of covering surfaces with towels or sheets, which can soak through and need washing. Keep your chapstick handy : There's nothing worse than ending up with stripes of color on your forehead. Rather than using a goopy salve to protect skin from dye, glide a clear solid lip balm along your hairline, Hill says: "Its small size makes for concise application."
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.
