Bonacure pH 4.5 Colour Freeze Micellar Silver Shampoo is brought to you by Schwarzkopf Professional. A Silverising Shampoo that gently yet effectively cleanses grey or lightened hair, while protecting it from yellowing.

Its exceptional formula is designed to lightly distribute a blue-violet dye through the hair, preserving and reviving cool tones. While devised to neutralise unwanted warmer undertones. Cell Perfector Technology seals the cuticle, while adjusting the hair to its optimal pH value of 4.5, colour pigments are frozen deep inside the hair fibre, ensuring colour vibrancy.

White hair benefits from the addition of a subtle, silver shimmer. For optimum results, follow with the pH 4.5 Colour Freeze treatment of your choice.
