This Amino Bond Shampoo, Conditioner & Intense Rebond Treatment system penetrates deep into your hair to help strengthen each strand and its bond from the core. When hair damage occurs, bonds break, and amino acids are lost throughout your hair, from the core to the outer cuticle layer. The Amino Bond collection is designed specifically for damaged hair and can help repair up to 5 types of hair damage in minutes. Our lightweight leave-in serum delivers our exclusive ProteinFusion blend with 5 amino acids and keratin protein that penetrates deep to rebuild and strengthen bonds. Our patented bond-building technology rebuilds broken bonds and generates new ones. The Amino Bond Intense Rebond Treatment is designed to mend split ends while helping to repair up to two years of protein loss after one use — leaving hair stronger and more damage-resistant. The Nexxus collections are scientifically proven to support hair health over time. Our formulas are crafted with our exclusive H4 Complex and help restore and protect the four signs of hair health: moisture, strength, shine, and elasticity. How to use: Massage the Amino Bond Shampoo into the scalp, lather, and rinse. Then spread this repairing conditioner throughout wet hair and rinse. Then, work the serum evenly throughout your hair. Don’t rinse out the treatment. After it’s set for three minutes, the bond building will be activated, and it will continue to activate as your hair dries.
