Transform your color-treated hair care routine with Nexxus Color Assure Shampoo and Conditioner Set. This professional-grade duo is specially formulated using advanced protein science to extend color vibrancy while nourishing and strengthening your hair. Our exclusive ProteinFusion blend combines Elastin Protein and Quinoa to create an invisible defensive layer that protects essential proteins within the hair fiber. This innovative formula helps lock in color for up to 40 washes while providing deep moisturization and anti-breakage protection. The Color Assure Shampoo gently cleanses without stripping color, while the matching conditioner seals in vibrancy and smooths the hair cuticle. Enriched with Sweet Almond Oil, Hydrolyzed Keratin, and Wheat Protein, this system strengthens hair from within while maintaining the integrity of your color investment. Perfect for all types of color-treated hair including highlights, lowlights, balayage, and full color applications. The formaldehyde-free formula is gentle enough for daily use yet powerful enough to deliver salon-quality results at home. Each set includes 32 fl oz of Color Assure Shampoo and 32 fl oz of Color Assure Conditioner (64 fl oz total), providing exceptional value for long-lasting color protection and hair health.
