I applied a permanent color 'black' about a month ago. Before that my hair was a shade of brown burgundy also a permanent dye... however my local store stopped selling it so I opt for a different brand that gave me poor results so being that I was unhappy with the color... I felt I would just dye it black to 'fix' the problem. I used henna some months before permanantly dying my hair and liked the results just felt the process was messy so now I really want a nice burgundy like tint but am concerned with another chemical process as I don't want to overprocess my hair. So, finally my question : Can I use a hair remover to remove the black permanent dye then apply the henna over it? Or am I going to end up with green hair? Please help thanks!
