Nexxus Color Assure Shampoo for Color-Treated Hair, 33.8 fl oz — Sulfate-Free, Protects Vibrancy up to 40 Washes

Nexxus Color Assure Shampoo is a sulfate-free cleansing formula that helps lock in salon color and maintain vibrant, multidimensional tone for up to 40 washes.

Color-treated hair loses shine and intensity when the protein structure that holds dye molecules is weakened by chemical services, heat, and daily wear. Nexxus applies protein science with CHROMABOND SEALER technology and citric acid to reinforce keratin, smooth the cuticle, and create an ionic seal that helps keep color molecules in place. The result is cleaner, softer hair with stronger color retention and a reflective finish.

How does this shampoo protect color between salon visits?

The formula combines citric acid bond-strengthening agents with an ionic sealing complex to reduce color loss caused by water exposure and cuticle lifting. Regular use helps form a hydrophobic layer that slows pigment diffusion and preserves tonal clarity.

• CHROMABOND SEALER technology targets color-binding within the hair protein matrix
• Citric acid helps reseal raised cuticles after chemical services
• Sulfate-free cleansing that avoids harsh stripping of color molecules

Will it repair damage from dyeing and styling?

This shampoo is formulated to address color-induced protein disruption rather than just surface conditioning. It helps rebuild bond integrity, detangles, and smooths the cuticle to reduce frizz and brittleness that accelerate fading.

• Protein-focused ingredients help restore strand performance
• Improves manageability for easier styling and less breakage
• Works as part of the Color Assure system with the matching conditioner for best results

How quickly will I see results and how long do they last?

Immediate effects include smoother, shinier hair and improved slip for detangling after a single use. With continued use as a system, color vibrancy and multidimensional tone are supported for up to 40 washes according to consumer testing.

• Instant shine and smoother texture from first wash
• Consumer-validated protection through repeated washes
• Best paired with Color Assure conditioner to maximize longevity

Is this safe for daily use and for all types of color-treated hair?

The shampoo is sulfate-free and designed to gently cleanse without aggressive surfactants that can strip color. It’s suitable for a broad range of color services, including permanent dyes, highlights, and color-treated tones, but always patch-test new products if you have highly sensitive scalp or recent chemical processing.

• 0% sulfates to limit unnecessary color fading
• Formulated to hydrate and create a protective layer on strands
• Safe for most color-treated hair types when used as directed
