Thanks for telling us that, Ilikemike65. My wrong assumption came from my stylist advising me to use demi-permanent but in a dark brown color, so I figured black demi permanent would be easier to get out too!
I use Color Gems, which says it will last for so many shampoos. But if I understand you correctly, that would not be the case with black?
I haven't really put it to the test because I get white roots and put more of it on before the 12 or 24 or whatever it is shampoos, so I am putting color on color, though not black!
