Greigh is a blend of a level 10 blonde and a level 6 brunette. She creates a stunning contrast of light and depth, resulting in a multi-dimensional lived-in look. The icy brightness of the level 10 blonde pairs beautifully with the rich, medium brunette tones of a level 6, offering a seamless mix of cool and warm tones. 

If you lighten a level 6 brunette to a level 9-10, we would recommend toning with Redken Shades EQ 10P (1oz) + 10NA (10z) + 10GI (1oz)
