Ok...i went to Sally's tonight and they convinced me to go with the Color Gems in Blue Black. So, I put that on my hair and i'm sitting under the dryer now!
I bought 3 boxes of the blue black and mixed with the 9 developer. It's a demi-permanent hair color and they said it should last 28 shampoos. He told me it might cause a little dryness, but I could deep condition.
After I washed it out, I didn't really notice any dryness...maybe a wee bit...but I've noticed more with a semi permanent color. So, so far...so good. The color looked black. I don't know if I can say I saw any blueness, but it was definitely a very deep, rich black.
I'll let you all know what I think after it dries.
Thanks everyone for the suggestions! They really helped.
