Nexxus Color Assure Long Lasting Vibrancy Daily Conditioner with Elastin Protein, 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 Protein Fusion blend infused with Elastin Protein and Quinoa along with other ingredients to create Color Assure formulas that result in long-lasting Color vibrancy for up to 40 washes. Nexxus is expanding the Color Assure range to include new formats that create an optimal regimen for Color care, making it easier for people to help keep their Color looking vibrant for longer.
