Nexxus Color Assure ProteinFusion Shampoo Silicone Free and Sulfate Free Shampoo For Color Treated Hair 13.5 oz, 2 Count

Nexxus Color Assure Shampoo and Condition 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. For best use, apply Color Assure Shampoo to damp hair, massage into rich lather, and rinse thoroughly. Follow with Color Assure Conditioner — apply to damp hair, leave for 3 minutes, and rinse thoroughly. 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! Our Color Assure range includes new formats that create an optimal regimen for color care. The range includes products like a shampoo, conditioner, cleansing conditioner, purple shampoo for blonde and silver shades, and a deep treatment masque. A leader in salon-quality hair products, Nexxus uses learnings from science and nature. We know that hair is made of almost 90% proteins, which is why we use advanced scientific methods to identify the protein needs of each hair type and create customized formulas with proteins to bring your hair back to life.
