Hey, well half a year ago I dyed my hair colour darkest brown, and it hasn't really faded much only a really little bit, it was supposed to be a semi-permanent hair colour, but I forgot that dark hair colour actually stays in, and I was hoping someone knew how to get rid of 6 month old hair colour, and I kind of liked when it was darkest brown, but I only kept it because I got told it looked nice (oh and my roots are a really dark colour now, I used to be a light ash brown/dark ash blonde hair colour) and I don't really have enough mony to go to a salon to go through to lighten it again and then again, but I some money, so please help me (if it helps I'm also from Australia)

You bleach it out. You can't really remove hair color, especially if it's permanent, without letting it grow out, lightening it, or bleaching it.
