Well I can share my experience, but I don't know I would recommend this path. I dyed my hair black for years. The only way I could change it was to bleach my hair. Therefore, I took it upon myself and I bleached my hair 3 times. Since my hair was pretty much orange, I had to just bite the bullet and dye it the brown color I wanted. It ended up working ok, since my hair remained intact on my head. However, it was very damaged. For several months after that, I deep conditioned my hair constantly and nurtured it in every way possible. Now, I am just growing out my natural colour and hair has never felt or looked healthier. So my advice would be, to dye it. But then condition the heck out of it.
