Ok, I had hi-lited, bleached and dyed my locs. After I sported the two tone look for a while, the black began to fade from my locs in the back. So I took out the black dye with a product called Color Zap, then dyed it fire red all over. It was gorgeous bcuz I had lots of different tones to begin with, but it didn't last. Reds never do! I didn't want to have to keep re-touching the color - especially since, in my opinion, the dye had begun changing my hair texture. So I decided to go back to black. After a lot of research on np.com, I decided to use Bigen hair color. I love it! My only problem is that I didn't buy enough. I went thru 6 boxes of the stuff and it wasn't enough. I plan to touch up the spots I missed, but for now I have a few red hi-lites ;)
