L'Oréal Majirouge contains Ionène G and Incell that strengthens and reinforces hair fibres whilst conditioning. Majirouge can lighten up to 3 levels and each shade gives perfect coverage of up to 100% white hair. Develops in 35 minutes. In 2015 L'Oréal developed an exclusive technology, a molecule called Carmilane to make those majirouge reds even richer! Carmilane forms an incredibly strong bond with the hair fibre which helps to secure the colour deep within it. The result is red with a unique, multi-dimensional structure with L'Oréal's best ever fade-resistance. L'Oréal Majirouge Rubilane patented technology delivers longer-lasting, pure, vibrant and intense reds and coppers. For best results use with L'Oréal Professionnel Stabilised Cream Oxydant.
