I died my hair black for halloween about 3 weeks ago. It was semi permanent black and said it washes out in 28 washes. I realize it takes longer than this because it is SOOO dark, but it isn't fading at all and I was wondering if any of this prell or color oops will make much of a difference. I have an upcoming event I would like to go to with not BLACK hair. Even a little fading would be nice. Any suggestions??
