Nexxus Blond Assure Purple Shampoo uses our exclusive PROTEINFUSION blend containing Keratin Protein and Violet Pigment to tone down brassiness on blonde or silver hair.
Since hair is 90% protein, we use advanced scientific methods to identify the protein needs of each hair type. At Nexxus, we create customized protein-rich formulas to bring your hair back to life. 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 infused with Elastin Protein and Quinoa along with other ingredients to create Colour Assure formulas that result in long-lasting colour vibrancy for up to 40 washes.
