Not just the underneath part (which was once purple, then pink, then red), but the ENTIRE THING.
Step #1 - you gotta get all that pesky brown out, and bleach the shit out of it. For me, this took a while, since I had a lot of dark color to get out. Ugh, the chemicals. The CHEMICALS!


Step #3: Wait for a while, wash it out, then feel like an idiot-clown-mermaid.
I'm sure this color works on some people, but I didn't like it. It was just not me! AND I ran out of dye, so I missed a bunch of spots, AND the bleach didn't take to my ends very well so it looked icky and green at the ends... so... moving on to the next step...

Sigh.... at least I learned my lesson!
