4 Fascinating Things Every Woman Should Know About Gray Hair

"For most women, gray hair tends to be more resistant to absorbing color," says DuFour. "It may have something to do with the difference in texture." Your colorist may need to use a different formulation to get your new grays to take your favorite hair color. And you may need to reconsider what color you go with. "The hair color spectrum runs from level 1 to 10, 10 being the lightest blond and 1 being black," explains DuFour. "Levels 8 through 10, like light blonds, are not really designed to give you full gray coverage because they don't contain the pigment necessary to cover it up."
