Low-level ozone, formed by V.O.C.'s and U.V. light, is a chemically reactive gas that rapidly oxidizes and damages the dyes and pigments used in hair color. Metro3's exclusive Anti-Ozone Color Protection Complex serves as a highly effective barrier shielding hair from the dramatic color-fade associated with ozone exposure. Sleek Straightening balm is formulated to straighten and smooth wavy/curly hair while providing long lasting hold and humidity resistance.
