Elastin Protein + Quinoa
Coloring hair damages and depletes your natural proteins and makes hair less vibrant, dull and flat. 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, Elastin protein and Quinoa, are key ingredients in Nexxus Color Care Color Assure's Color Safe Exclusive PROTEINFUSION BLEND, both naturally rich in the same amino acids lost during the hair coloring process. This colored hair shampoo replenishes essential natural proteins while keeping colored hair vibrant for up to 40 washes.
