I was supposed to do some lowlights on my hair yesterday with this black hairdye I had at home.
Problem was it didn't become black and when I rinsed it out the blue based black dye just spread all over leaving me a result of blue, green and grey tones matching the light brown color on the top of my head...
Complete failure! I decided to try once again and ended up with a black bottom, but otherwise, the same color gradation.
It's not THAT bad, but I rather go outside in another color so hopefully I can re-dye it this weekend..
