hi,
I am actually looking to shock my friends for Halloween this year because it is my last Halloween in college so i wanted to do something dramatic. anyways, I went to hot topic and picked up some raw hair color in jet black. I have always had the same hair color and was a little nervous when purchasing it because i totally love my hair color. Well the guy at the store saw my blonde multi faceted all natural hair color and assured me that this would come out in 10-12 washes. Now I am reading all these product reviews that are scaring the hell out of me about black hair color and even it being demi permanent is it going to come out of my hair in 10-12 washes and will it turn my hair gray or anything?:confused:

I would buy a wig then take any chances.

I have naturally highlighted blonde hair as well. I have tried this Raw Jet Black demi-permanent hair dye on a small chunk of my hair. Thus far (since I can't find the chunk anymore. XD) It washed out in about 8-10 weeks. But while washing out, your hair will most likely turn a strange aqua green for the remainder of the time after you start washing it. It hasn't left a stain that I can see, and I'm planning to do the same thing.
