Schwarzkopf Professional BC Bonacure Color Freeze Silver Shampoo actively supports and enriches the shimmer of cool colour directions. Enhanced with essential violet colour pigment that can even reduce warm colour undertones within the hair. Unwanted golden or yellow tinges are minimised by using Schwarzkopf Professional BC Bonacure Color Freeze Silver Shampoo. The hair is cleansed, while violet direct pigments fight the un-aesthetic warm undertones. Ideal for use on pre-lightened and cool colour treated hair. Applied onto white/grey hair, it gives healthy metallic touch and enviable shine. Directions for use: - Blonde hair: Work into wet hair and rinse out immediately. - Grey hair: Work into wet hair and rinse out after 1-3 minutes. Schwarzkopf Professional BC Bonacure Color Freeze provides not only up to 90% colour retention, but also 100% colour and shine, down to every single hair. It captures colour pigments for longer lasting colour shine, giving the hair surface a polished effect. The breakthrough Color Freeze formula seals the hair's surface, glazing pigments in place for long-lasting colour and maximum shine. At last, you can freeze-frame vibrant shades with 100% colour shine!
