I really wanted to go back to school with my hair light brown but I can't because I dyed my hair black 4 months ago and it has not faded. I have been using head and shoulders and baby shampoo but it has not work now I'm using dish soup right now but its not fading fast. I am trying to make it fade in a week. Does anybody know how to make it fade in a week?

I went to the shop and brought 1O lemons, squirted the juice into a jug, put it on my head for 4O minutes, washed it, shook vinegar on my head and then washed it again. Then the next day I used fairy washing up liquid then washed it again. My roots were pretty much through by the weekend(: hope this helps xxx
