I was thinking about using manic panic(Raven Black) but I couldn't find it. I'm just wondering if the manic panic will take over the henna, because I haven't been able to get any kind of color to take over my henna. I used the body art quality henna(Jamilla), I've tried several different brands of black rinses and none of them will take over my henna. My hair usually takes well to any kind of color but for some reason it can't get through the henna. I even tried clarifying before using my rinse. Good Luck!!!
