I just tried coloring my hair purple using a Splat hair kit. I have med. To dark brown hair. The first step was to use the bleach which I only used in a few places and didn't leave it in the full time. The second step was to add the thick purple gel. I eneded up with some parts really purple and others not colored at all. What can I do to fix it? I'm afraid to put any more chemicals in my hair, but don't want to spend $200 going to a professional to have fixed. Can I get another purple kit and try to get it covered better? Or, can I color my hair black to cover the purple? Please help!
