Banish grays and reclaim youthful-looking hair, with Keratin Color from Schwarzkopf. NEW Keratin Color True Blonde shades provide up to 100% gray coverage and up to 80% less breakage (vs. untreated hair). The protective pre-color serum conditions the hair before coloring for a more even color from root to tip and the K-Bond-Plex anti-brass purple conditioner works to neutralizes brass for a cool blonde effect while it repairs the inner hair structure for healthy looking hair. Color your hair with confidence and care – Keratin Color leaves your hair looking renewed, healthy, and strong! If your hair is longer than shoulder length, we recommend using 2 boxes of Keratin Color hair dye for the application.
