My hair is naturally dirty blonde/light brown. I ended up dying it about 4 months ago to a dark brown with L'OREAL Paris Healthy Look semipermanent hair dye. It was supposed to wash out after around 28 shampoos, but two months later my hair was still not back to normal, so I ended up re-dying it to a dark brown again. Since then I have tried everything to get it out. I used Prell Shampoo until it ran out, I've tried Dawn dish detergent, I've done more things, and I have even used Color Oops hair removal twice, but still my hair is not back to normal. Instead of being dark brown, it's now a medium/light brown, but I just want it to come out because my roots are coming back in. I don't want to dye my hair again, even if it's similar to my natural color, because I'm afraid it still won't look right and I just want it to be natural. Is there anything else I can do?
