i am a twenty nine year old woman with black hair to suit my fair complexion. i had previously dyed them from blonde to black,and now i am thinking of changing my hair color again,but my sister tells me that i should avoid totally coloring my hair and that why dont i use Copper Highlights if i want to and the combination willl look good.can someone tell me that whether they have tried copper highlights in black hair?i hope to know if there are such people?and that how much does it cost for incorporating Copper Highlights in black hair?this will help in getting a makeover with a twist of color in it.
