Nexxus Color Assure ProteinFusion Shampoo
Nexxus Color Assure Shampoo has been specially formulated to help extend the color vibrancy of color-treated hair longer. Using our exclusive ProteinFusion blend, this sulfate-free shampoo cleanses color-treated hair and helps replenish nutrients to help enhance color vibrancy. Nexxus scientists used Proteomics studies to examine hair damage at the molecular level and found that the main cause of color loss and dullness is hair coloration. With this knowledge in mind, our scientists developed a one-of-a-kind ProteinFusion blend 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.
