Got my highlights done in a very Expensive salon as decided to treat myself ! Long story short they hadn’t patch tested me for a root colour for a root smudge ! Had to go back today for root smudge and the girl has basically put the root smudge on and loads of dark lowlights which are slightly coppery ! I looked better going in than out! How can I. Get this dye out quickly ? Any good shampoos for use in house to do this?
