Wash your hair a couple of times with dish soap however use a lot of conditioner after, this will fade the color.Any ideas on how to make a black hair color job fade.?
All I can think of is strip your hair, go to a beauty salan they can do it. I dyed my hair black a few times and that's what I had to do. It's the only way to get the black out of you hair, unless you wait for it to just grow out.
lots of sun


the sun naturally makes your hair lighter then is tone





if you got it professionally done


washing wont help that much


well not in a short period of time at lest





worse comes to worse


go to a drug store and dye over it


to a soft black color
