Nexxus has progressed Colour Assure, one of its top-selling collections, to incorporate teachings from science and nature and introduce new products – with a new look – to help extend colour vibrancy for longer. After using Proteomics studies to examine hair damage at the molecular level, Nexxus scientists found that the main cause of colour loss and dullness happens the moment hair is coloured. Our scientists have developed a one-of-a-kind ProteinFusion blend with Elastin Protein and Quinoa to create Colour Assure formulas that result in long-lasting colour vibrancy for up to 40 washes. Explore the Colour Assure range and our new formats that create an optimal regimen for coloured hair care, making it easier for you to help keep your colour looking vibrant for longer. The range includes a shampoo, conditioner, cleansing conditioner, purple shampoo for blonde and silver shades and a deep treatment masque. At Nexxus, we know that hair is made of around 90% proteins, which is why we use advanced scientific methods to identify the protein needs of each hair type. We create customized formulas, with proteins, to provide excellent hair treatment.
