L'Oréal Professionnel Vitamino Color Spectrum Green Tinted Shampoo is the ultimate solution for neutralising red undertones in dark brown, colour-treated hair. Formulated with Ferulic Acid and Citric Acid, this professional shampoo enhances shine, nourishes hair, and locks in salon-fresh color for up to 100 days. The green pigment technology counteracts warm tones, ensuring a deep, rich brown shade without brassiness. If you have dark brown, colour-treated hair, the L'Oréal Professionnel Vitamino Color Spectrum Green Tinted Shampoo is a must-have in your haircare routine. Unwanted red and warm undertones can appear over time in coloured dark brown hair due to oxidation, sun exposure, and frequent washing. L'Oréal Professionnel Vitamino Color Spectrum Green Tinted Shampoo is expertly designed to neutralise these red tones, preserving your cool, deep brunette shade for longer. With a creamy, sulphate-free formula, this professional shampoo gently cleanses while enhancing all five dimensions of colour: - Shine: Leaves hair with an ultra-glossy, mirror-like finish. - Saturation: Helps retain rich, salon-fresh vibrancy. - Contrast: Maintains multi-dimensional depth in dark brown shades. - Tone: Instantly corrects red undertones, restoring a true brown hue. - Brightness: Keeps light-to-dark balance intact for a well-defined, rich colour. This L'Oréal Professional shampoo for coloured hair contains a powerful Ferulic Acid + Citric Acid complex that locks colour into the hair fibre, preventing premature fading while strengthening and protecting strands. Designed for use two weeks after salon color, this professional shampoo works best when alternated with the Vitamino Color Spectrum non-tinted shampoo.
