Review (1/5): Not much help with brassiness
We used this on long hair that was mostly previously bleached and with 3" of newly bleached roots that were a lemon yellow color. We hoped to remove the yellow on the newly bleached areas, but the affect was minimal. It still looked yellow, just a little less so. We tried several similar products and had similar results, so I suspect that we just are dealing with hard-to-tone hair. In the end, we had to use a semi-permanent dye in a darker shade. This product did, however, have a nice conditioning affect.
