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 and vitality of colour treated hair, this rich formula gives damaged and porous strands the extra care they need. An Ionic Shine Booster ensures that your colour looks lustrous and 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, and rinse away thoroughly. Follow with the Color Freeze Conditioner.
