The answer is yes.

I color my hair. I do the roots every month and refresh the length every 6 months. I only use a 10 Vol developer - which is maximum deposit with minimum lift. A girl's gotta chase the grays. But I stick with the same level every time - level 3 - very dark.

The most coloring damage happens when you LIFT color - especially if you go dark, then back to light and all over the place. Even lightening of virgin hair is damaging. But bad things happen when you can't make up your mind!
