Shu Uemura Colour Lustre Shades Reviving Balm This purple Shu Uemura Colour Lustre Shades Reviving Balm ($58) goes on after you shampoo and works especially well at intensifying more platinum tones. Both the Cool Blonde and Golden Blonde options can also help colour-treated blond hair last longer between salon trips because there's protective musk rose oil inside as well.
