I have hard water and I usually dye my hair at home and I could never rely on my hair to come out looking like the color it was supposed to on the box. Even when I would get my hair colored at the salon a few times a year, my stylist would have to take extra steps to get the color to look right and take well. Then I found Malibu C Color Prepare treatment and I can't believe how much better my hair color results are now! Color Prepare is literally amazing! I no longer have the anxiety of wondering what shade my hair color will turn out when I dye it at home. I really love the Color Prepare treatment. It's totally gentle on my hair and I won't dye my hair without it now.
