Copper is naturally present in our hair. But if there is an excess amount, it can cause sensitization and breakage of the hair fiber during the color process. Metal also influences the way that colors turn out, sometimes making the final results unpredictable and less successful. By identifying the presence of copper not only on the surface but also within the hair fiber, L'Oréal’s researchers developed a new technology capable of neutralizing these copper clusters within the hair.
This innovation, which has been incorporated in the Metal Detox range by L’Oréal Professionnel Paris, is revolutionizing hair color. It offers a new routine that allows stylists to color and bleach with total confidence and achieve reliable results, all while looking after their customers’ hair.
