With 40% less protein than thick hair, fine hair is 10x more prone to breakage. Our experts created our Unbreakable Care™ collection to strengthen fine hair by harnessing the power of Arginine amino acids, which have nearly 2x more inner core-strengthening properties. We used these findings to source natural proteins that are high in Arginine amino acids and created a system with Advanced Keratin Protein, Collagen, and Biotin to deliver stronger, fuller, thicker-looking hair.
Using advanced protein science to examine curly hair at the deepest molecular level, Nexxus scientists identified that certain proteins appear with two to six times greater frequency in curly hair than in straight. That’s why we created our exclusive formula infused with Silk Protein to replenish curly hair follicles and Marula Oil to provide intense moisture to curly and coily hair. This game-changing blend delivers the perfect balance of moisture, strength, and flexibility.
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 process --- 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. Enter Therappe and Humectress which is infused with our exclusive PROTEINFUSION blend of green caviar + elastin protein to go beyond moisture to restore nutrients in every strand. 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.
Nexxus Blonde Assure Purple Shampoo and Conditioner uses our unique PROTEINFUSION blend of keratin and violet pigments to correct brassy tones and enrich bleached, platinum or silver hair to give a natural or intense look to any blonde shade.
