A stylist (different than my usual one) was telling me the other day about a grey-coverage technique that she learned at a TIGI workshop.
She said that you first saturate they hair with only the color (no developer). Then, you go over it with the normal formula (with developer). I can't remember whether or not it is supposed to be washed in between these two steps. She said that it is supposed to help with grey coverage.
I am wondering if any professionals have tried this and recommend it as a coverage technique. Also, I was wondering which professional color is best for grey coverage.
