How Color Affects the Hair

Coloring hair can damage your hair’s natural proteins and make hair look less vibrant, dull, and flat. Our Color Assure collection, including our shampoo and conditioner for colored hair plus hair mask, is designed to replenish your hair with the nutrients and protein building blocks it loses during the coloring process.

A microscopic view of the various ingredients are shown in a container sitting atop a pink background.

Our Color Safe Ingredient Blend

Using advanced protein science, Nexxus scientists identified the amino acids that make up the proteins lost most during the hair coloring process: Cysteine, Glutamic Acid, and Serine. With this discovery, our Color Assure ProteinFusion™ blend was specially formulated with Elastin Protein and Quinoa to replenish each strand and keep colored hair vibrant.
