Help and advice please, I have tried to have my blond dip dye blended in. The base was a wella colour touch 6.0 mixed with 4% which Inhave used for years. It has gone orange at the salon I went to. Should I attempt to lift again with powder bleach & 40% or put my old 6.0 brown on it....or neither....any help and advice would be much appreciated. Thanks in advance
