HELP!! My natural color is darkish blonde, and I wanted to go lighter blonde, so dyed my hair a frost blonde color, but I either didn't leave the dye on long enough/not long enough and it went ginger! So I tried to hide the ginger by going a lightish brown, so now it's not as bright a ginger as it was,but it's still ginger and the roots are even more noticeable than the actual hair. I've already spent loads on hair dye, and apparently stripping isn't a good idea, any ideas? Or any ways I can get the hair dye out without stripping it?

Yes, get a very short hair cut before you damage hair follicles and scalp and don't have any hair at all.
