Nexxus Unbreakable Care Anti-Breakage Shampoo and Thickening Conditioner set, 32 fl oz each, 2-pack. This sulfate-free haircare system is specially formulated for fine and thin hair to reduce up to 97% of hair fall due to breakage while helping to build fullness and strength.
The ProteinFusion Blend contains Advanced Keratin Protein, Biotin, and Collagen Amino Acids, ingredients all high in Arginine, which provides 2x more inner-core strengthening properties. This scientifically proven system strengthens the hair fiber's inner core from root to tip, helping prevent breakage and leaving hair visibly fuller. The shampoo gently cleanses while the thickening conditioner adds weightless moisture and volume.
Powered by exclusive micro-thickening technology that creates weightless, thickening bonds between strands for stronger, fuller, thicker-looking hair. The hydrophobic barrier weightlessly wraps around each strand to block out frizz in up to 98% humidity. Designed for all fine and thin hair textures to restore strength from within, filling in holes and cracks in the outer cuticle while restoring its healthy condition.
