2X - Nexxus Color Assure Sulfate Free Shampoo For Color Treated Hair - 33.8 fl oz

Nexxus Color Assure Shampoo for color-treated hair has been specially formulated to help extend the color vibrancy of color-treated hair for longer. Using our exclusive PROTEINFUSION blend, this sulfate-free shampoo for color treated hair helps replenish nutrients to help enhance color vibrancy. For best use, apply this silicone free shampoo with pump to wet hair. Later, rinse and follow with Nexxus Color Assure Conditioner. 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 regiment for color care. The range includes products like a shampoo, conditioner, and 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.
