Nexxus Long Lasting Vibrancy Shampoo 3.0 fl oz

As a leader in salon quality products, Nexxus has progressed one of its top-selling collections, Color Assure, to incorporate learnings from science and nature, and introduce new products - with a new look - to help extend color vibrancy for longer. After using Proteomics studies to examine hair damage at the molecular level, Nexxus scientists found that the main cause of color loss and dullness happens the moment hair is colored. Our scientists have developed a one-of-a-kind ProteinFusion blend infused with Elastin Protein and Quinoa along with other ingredients to create Color Assure formulas that result in lasting color vibrancy for up to 40 washes.
