Schwarzkopf Bonacure Color Freeze Shampoo pH 4.5 is specially formulated to protect and maintain the vibrancy of colored hair. Its balanced pH helps to seal the hair cuticle, locking in color and preventing fading. This gentle yet effective shampoo cleanses without stripping essential moisture, leaving hair smooth, shiny, and color-intense for longer-lasting results.
