I am not a colorist - so I am just passing along what I have been told. Color won't remove color - so if you want to go lighter over previously colored hair you will have to use a lightening agent (bleach etc.) Also, hair color does process more quickly at the roots due to the heat from your scalp. Or so I've been told.
