So I was at the store a few months ago with my gf when she was buying hair color and I thought, hmm, I wonder how my hair would look darker, so I picked up some "temporary" hair dye in dark brown/black and thought I'd try it out. Since the packaging says it comes out in 28 washes anyway, I figured I didn't have much to lose. Well, it didn't wash out after many more than 28 washes and I was getting bored with the color so I tried to buy some light brown/medium blonde color and restore it to my original shade. That did nothing except to dye my roots a shiny, vibrant brown color and leave all of the black the same. Now my hair has grown out some more and I have three colors: the natural color, the brown and the black growing out in that order. What options do I have to fix this? Can a salon bleach my whole head and then put in a new color on top of that or will the black resist any treatment that I try and have done except just cutting it off and going short for summer? Is there a way to fix this at home inexpensively or is spending $100+ at Toni and Guy going to be my only option?
