Silver Hair Dye Semi Permanent Icy-cool tones give this seriously metallic shade of Silver a breathtaking shine. Alternatively, dazzle differently by using Silver to tone away any unwanted yellow in your hair. For the most vivid results, we recommend applying to pre-lightened hair. The colour on the pot is a simulation of the colour on a level 10. Soft, silky hair never goes out of style. That’s why all our colours contain a conditioning formula that nourishes hair from first application
