When hair is over-processed, it needs the nourishing touch of the Schwarzkopf Professional BC Bonacure Color Freeze Rich Shampoo. Created to restore the strength & vitality of colour treated hair, this rich formula gives damaged & porous strands the extra care they need. An Ionic Shine Booster ensures that your colour looks lustrous & glossy, while the core ingredient of the Color Freeze range, reactive silane, provides up to 90% colour retention. Apply to damp hair, work into a lather, & rinse away thoroughly. Follow with the Color Freeze Conditioner.
