So, I've been dying my hair for a while, always a dark brown shade, and each time it fades to a brassy-reddish brown color. I was wondering if using a dark ash brown would get rid of this reddish color? Does anyone have any experiences with ash hair dye?? Also, if I use it now with a reddish tinge to my hair would it turn my hair green? I heard ash can make your hair look green, is it true for dark shades too?? I'm so confused with hair dye tones... and I can't afford to go to a salon.. so any one have any tips/advice?!? TIA!
