After conducting product testing with the black and white Zylist prototypes in different colors of hair, we’ve found the white prototype outperforms the black in terms of visibility of the hair within the tool. To explain: to align one cut with the next, you visualize the hair through the clear paddle and align your last cut with the dotted line. Visibility is best when the hair and the background have the greatest degree of contrast. Turns out almost all hair, even light blonde, shows up well with a white background. We want everyone, no matter what color hair, to have a great experience with the Zylist. And we think everyone will get that experience with white. So it's decided - we're launching with white!!
