Co-developed with professional haircare experts and formulated with patented Glicoamine technology, the L'Oréal Professionnel Serie Expert Metal Detox Shampoo helps to neutralise excess copper in the hair. Excess levels of metal can be absorbed through your shower water and found in your hair, causing visible breakage and colour fading. This high-performance formula acts as a magnet to draw out impurities and gently cleanse the hair to remove any harmful metal particles, while offering protection from further visible damage. Hair is left feeling intensely nourished and smooth, adorned with a high-shine finish.
