At Nexxus, we know that hair is made of around 90% proteins, which is why we use advanced scientific methods to identify the protein needs of each hair type. We create customized formulas with proteins, to bring your hair back to life. The Nexxus Color Assure Long Lasting Vibrancy System for Color Treated Hair, with Elastin Protein and Quinoa, keep your color vibrant. Colored hair can lose its vibrancy over time, but repeating the hair color process is not the answer. After using Proteomics studies to examine hair damage at the molecular level, Nexxus scientists found that the main cause of color loss and dullness happens the moment hair is colored. Coloring hair can destroy proteins and weaken the fiber, leaving hair feeling flat and like it has lost its shine. Our scientists used an advanced scientific method called Proteomics to measure what proteins and amino acids are damaged in the hair fiber when hair is colored. The main amino acids lost during the coloring process are Cysteine, Glutamic Acid and Serine, in combination. This then allows us to design formulas to help strengthen and prevent dull hair.
