Hi I was hoping for some help, I applied igora colorworx purple over my full head of pl highlights assuming it would wash out eventually just like pink etc but it just washed to a teal colour, I reapplied a couple of times but massive maintanance. Since that I have done used a bleach bath with 30vol... still teal. I then pre pig'd and applied a 6.0 but after 1 wash green showed through. I then did a B4 colour stripper, it stripped everything but the teal, finally I applied a 7.77 and 7.64 with 10vol but after 1 wash I see green again. Any advice please? I'm at a loss on what to do now. Also I done a strand test with pl and 40vol today it just lifted to teal again
