Nexxus Color Assure Shampoo for Color-Treated Hair, 33.8 oz — Sulfate-Free, Chromabond Sealer for Up to 40 Washes

Nexxus Color Assure Shampoo is a sulfate-free cleansing formula powered by CHROMABOND SEALER and citric acid that helps lock in hair color and shine for up to 40 washes.

Color-treated hair needs targeted care to preserve tone, gloss, and strength. Nexxus built Color Assure around protein-focused science that repairs color-induced damage while sealing the cuticle so color molecules remain inside the hair shaft. The result is smoother, more reflective hair with reduced fade, frizz, and dullness after chemical color services.

How does this shampoo protect color without stripping it?

The formula uses CHROMABOND SEALER technology and citric acid to reinforce protein bonds and close the raised cuticle that occurs after color processing. By creating an ionic sealing layer, the shampoo reduces color diffusion during washing and exposure to water.

• 3.3% Chromabond Sealer complex targets color retention at the protein level
• Citric acid helps reseal and smooth the cuticle after coloring
• Sulfate-free surfactants cleanse without harsh color-stripping detergents

Will it make my colored hair shinier and smoother in one use?

Yes—this system is formulated to deliver immediate shine and manageability while working cumulatively to protect color over time. In a single wash it detangles, smooths, and increases surface reflectivity for a noticeable boost in radiance.

• Instant smoothness and reduced frizz after first use
• Hydrating ingredients add softness and easier styling
• Sealing action improves light reflection for enhanced color luminosity

How long does color protection last and what does ‘40 washes’ mean?

When used as part of the Color Assure shampoo and conditioner system, the technology is designed to preserve color vibrancy through repeated washes — the brand reports protection lasting up to 40 wash cycles under normal home-use conditions. Individual results vary with water type, styling practices, and frequency of washing.

• Designed to maintain chromatic depth and tone across many washes
• Works best combined with the matching conditioner for full sealing benefits
• Performance depends on styling heat, UV exposure, and chemical history

Does this help repair color-related damage and reduce breakage?

The product focuses on restoring protein integrity that color services can weaken. By strengthening bonds and smoothing the cuticle, it helps improve strand resilience and manageability, reducing the appearance of damage and making hair easier to comb and style.

• Protein-based approach repairs color-induced weakening
• Smoother cuticle lowers tangles and mechanical breakage during styling
• Added moisture improves flexibility and reduces dryness

Who is this for: Nexxus Color Assure Shampoo is aimed at anyone with color-treated, highlighted, or chemically lightened hair who wants to extend dye vibrancy, reduce fade, and improve hair surface shine and manageability. It’s ideal for people seeking a sulfate-free cleansing system that supports protein repair while sealing in tone, but those with very fine or oil-prone scalps should adjust frequency of use as needed.

Usage tip: Massage into wet hair, rinse, and follow with Nexxus Color Assure Conditioner to complete the sealing and hydration system for best color retention.
