Nexxus Color Assure Shampoo and Conditioner for color-treated hair has been specially formulated to cleanse hair gently while extending color vibrancy. Using our exclusive PROTEINFUSION blend, this sulfate-free shampoo and hydrating conditioner help replenish nutrients, providing long-lasting color vibrancy for up to 8 weeks or 40 washes. 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.
