I put a permanent hair lightner on my hair and it's gone wrong will a dye cover it ??

I think so, but l think it would be better to use kana hair dye which is natural and is stronger than any dye and it would surely cover it. But the thing with kana is that ,as l said it is stronger than regular hair dye, when you use it you wont be able to redye your hair again for a couple of months because it wont cover it..
