I have been dyeing my hair since I was 16 years old, I'm now 20. I first started with blond highlights and a dark brown base, then I changed it to a dark red, then dark brown, and currently it is a reddish brownish color that I don't like, but I don't want to dye it again. My hair is so damaged that it will not grow at all. I was wondering if I should strip the color from my hair? Would that help my hair get healthy again? Or what can I use to get my hair to be healthy again?

Stripping your hair will make your hair extremely brittle it will not make your situation any better.

I would recommend going to your local salon and seeing if they offer a deep conditioning treatment. You need o get your hair healthy again before you start dyeing it more.
