Can ANYONE HELP! I’m new to wella and used wella kp 22/81 on my natural red root base 7 and old bleached mid length and ends and wow I have purple hair! It’s actually not to bad on the ends ( after washing 3 times) but the roots haven’t even touched so there a different colour to the rest of my hair . Going forward as my roots grow more what should I use and any recommendations on what to do with the purple bits ??
