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. #AFProTip: If your hair is very light cool blonde but not quite platinum, try mixing Sterling with a little bit of a warmer tone like Girl's Night to help cover blonde undertones more effectively. Or, you can mix a bit into Poseidon, Purple AF or a few other shades to give that color a smoky hue! Made only from vegan ingredients with no animal by-products.
