I just dyed my whole head black yesterday and I HATE it. I used to have dark brown w/ black underneath. When I washed it out, only the front and underneath was black, the whole back of my head was still brown. Also, about the last 2 inches of all of my hair is my natural hair color, light brown. How do I fade the black fast without stripping it? I've heard about prell and dish detergent, is that over like a week or longer? How long will it take to come out?

Black is the hardest color to Get out of your hair.. If you can wait a little Use different types of hair products like Hairspray,gells and such it sucks the color out Deppends on what product you used to dye your hair with? Herberil essances Lorial? Sorry bad spelling >.< Shampoo also gets the color faded and those are some healthy ways to get it out
But if you really want it out Fast Mix Bleach in your shampoo or just Get a Bleach kit
Start from the tips and work your way to the roots it should get your Hair color
Brownish,orange,blonde it will look scary but you'll have to Dye over it in acouple of days
Good luck :)

I have baking soda w/ shampoo soaking in my hair right now so hopefully that will work. I heard that it's easiest to removed dye in the first few days, I just dyed it last night, so I hope it'll come out. I used herbal essences black stilletoes.
