I've been box dyeing my hair for quite a long time, it's always been a dark brown with a tinge of red, I wanted to go to a medium ash brown. I went to a hair dresser and she did a bleach bath and put a mediumish brown over it after... it turned out an AWFUL red. Then I bought ash brown hair color on two occasions after and dyed my hair two seperate times. It just made it darker. At this point I'm unsure of what I should do to get to the color I want. If I should use the colour b4, then tone(I know next to nothing about toners) or color. Any advice is greatly appreciated! also I am located in the US.
