This Schwarzkopf product is a gentle pre-treatment wash that is specially created to wash and protect the hair fibers. Designed primarily to care for grey, white or bleached hair, it helps to give it the ideal pH value. Its components allow pigments to be better trapped in each fiber and thus achieve a natural shine in ashy tones, preventing them from turning yellowish. Recommended to neutralize chemical residues that may remain after colouring, it is ideal for daily use. It helps to maintain vivid and intense colours for a longer period of time, softening the hair and making it easier to comb. It is available as a mattifying shampoo. This corresponds to the 250ml bottle. It can be used by both women and men with highlights, grey hair or ashy discolourations.
