I've been through five different colors in the last eight months and currently my hair is two toned and it bothers me. I dyed my hair black this summer thinking it would be able to leave it alone and like it grow out. I have only 4 or 5 inches of hair when it's stretched out so I'm still at a point where if I feel like its too damaged I can't shave it and start over. I plan to bleach my hair tonight to get rid of the two toned. I've thought about using a black rinse but I co wash daily and it would be a waste.
