eCosmetics is an authorized retailer of Arctic Fox.This light gray works well for any silvery, steely look.To achieve this pastel silver, your hair needs to be platinum at a level 11+. Pre-lightening is a must with this shade! Since toner deposits color, refrain from using it to achieve level 11 blonde; if you do tone level 10 hair and then add Sterling, it can create unwanted pigment interactions or inconsistent color. Any yellow tones in blonde hair can interact with the blue/silvery base in Sterling to cause an unpredictable result.
