Bleaching, chemical process, and rigorous heat styling is very harsh on hair and can severely damage it both inside and out. Using advanced protein science research and testing, Nexxus scientists identified Glutamic acid as the key amino acid hair protein loses when it is severely damaged. With this discovery, Keraphix's transformative PROTEINFUSION blend includes black rice (a rich source in Glutamic Acid) and strengthening keratin protein to create a healing ritual that delivers clinically-proven healthier looking hair in one use.
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 coloring processs---Cysteine, Glutamic acid, and Serine. With this discovery, Elastin protein and Quinoa, are key ingredients in Color Assure's exclusive PROTEINFUSION BLEND, both naturally rich in the same amino acids lost during the coloring process. It replenishes essential natural proteins while keeping colored hair vibrant for up to 40 washes.
During the day even healthy hair loses moisture naturally, leaving it dull and lifeless.

This system is designed to give dry hair deep hydration while fortifying the surface, restoring natural protective barriers that lock in moisture for 24 hours.
Using advanced protein science to examine fine and fragile hair at the deepest molecular level, Nexxus scientists identified that healthy and strong fine hair is rich in the amino acid, cysteine. With this discovery, the Scalp Inergy system is scientifically crafted with a fortifying PROTEINFUSION™ blend with wheat protein, a rich source of cysteine, and ginger root, a known scalp energizer. It nourishes the scalp where strong, healthy hair starts, while making fine hair 4X's stronger against breakage in 1 use.
