I find that this color mostly covers but it is 'dimensional' ie: blends gray. So most will be covered but the rest will be blended instead of covered. If you want it eliminated you want to use Redken Color Gels or Color Fushion.

CHECK THE AMMONIA LEVELS
Companies like Redken, say low ammonia, but in reality, they are using a cousin of ammonia. I believe Redken color starts at a high ammonia level when better profession colors have .7 %ammonia and are honest about it
