Schwarzkopf Professional BC Bonacure pH 4.5 Colour Freeze Micellar Silver Shampoo (250ml) gently yet effectively cleanses grey or lightened hair and protects it from yellowing. Lightly distributing a blue-violet dye through the hair, it preserves and revives cool tones whilst neutralising unwanted warmer undertones. White hair benefits from the addition of a subtle, silver shimmer. Cell Perfector Technology seals the cuticle and by adjusting the hair to its optimal pH value of 4.5, colour pigments are frozen deep inside the hair fibre, ensuring colour vibrancy.
Directions of use:
• Apply to wet hair. Work into a lather, rinse and repeat if necessary.
• For optimum results, follow with the pH 4.5 Colour Freeze treatment of your choice.
