Black hair dye stripping advice?

Background first. I've been dying my hair black for roughly a year now, and I've dyed it black multiple times. I was so stupid when dying it because I never thought of the fact that It'd be a pain in the *** to remove it. Anyway, I decided to try the Color Oops hair dye stripper, and the result was the top portion of my hair being an orange/blonde color, and the bottom being a dark brown, I was not shocked, I expected this result because I've dyed the bottom more, and only dyed the top a couple times when my roots grew. I dyed the top part a dark brown to match the bottom part, and it looked fine, although i was upset because it really looked like I didn't do much to my hair, it was only a few shades lighter.
NOW: It's a few months later and I want to know if anyone recommends stripping it again? Would it make a difference?( I'm not worried about the damage it would do, I take very good care of my hair.) I just want a lighter brown color, like i intended on when i first stripped it.
