Hi, I have jet black hair. I'm afraid to put in permanent hair color, mostly of it ruining my hair and I don't want to worry about keeping up with new growth. However, my hair is just too blah and I want to add a tint of red to it. I tried both semi permanent, and today I tried a demi permanent level 5 color. But my hair did not pick up the color at all. I know of other that have black hair but was able to color with a demi. Am I doing something wrong here? Any suggestions?
