Shampoo specifically formulated for toning cool blondes, gray and unpigmented hair. ARCTIC GRAY Shampoo neutralizes intense yellow and light yellow underlying pigments after coloring or lightening processes without leaving unwanted effects. You can use the shampoo to eliminate yellow from gray and unpigmented hair without staining or leaving residues. On platinum or ultra platinum hair, it cools down the tonality, leaving a natural ash reflection.
