I dont mean anything by it at all. I was just using it as an example of a "two-toned" dye job.
My point from the above thread is that that number of colors your hair is dyed
doesnt affect what products you can use. The only exception I could think of is in the realm of color depositing shampoos. If your hair was ALL red or ALL black it would make sense to use a color depositing shampoo (red or black, respectivley), because the color would be deposited to all the hair evenly.
However, say you had two-toned hair... (I'll use you as an example, slatka) with both blonde and black hair, and say for whatever reason you wanted to use a color depositing shampoo so your black hair didnt fade. This would be fine for your dark hair, but it would mess up your blonde hair by giving it a dark tinge. get it?
