Nexxus Color Assure Color Care Shampoo & Conditioner Duo for Color-Treated Hair — 2-Count (33.8 fl oz), Chromabond Sealer

Nexxus Color Assure is a salon-grade shampoo and conditioner duo formulated with Chromabond Sealer and citric acid to lock in color vibrancy and smooth the cuticle for up to 40 washes.

Whether you leave the salon with a fresh dye or maintain highlights at home, color-treated hair needs gentle, targeted care to stay luminous. This two-count system—full-size shampoo and conditioner—combines protein-focused repair with sealing chemistry designed to protect pigment, reduce color diffusion in water, and restore surface shine. The formula is built on Nexxus’s protein science heritage and aims to strengthen hair where color processes weaken its structure.

How does this shampoo and conditioner keep color from fading?

The Chromabond Sealer technology pairs with citric acid to re-form and reinforce protein bonds, sealing the cuticle so color molecules remain trapped in the cortex rather than washing out. Ionic sealing creates a hydrophobic surface that reduces pigment loss during rinsing and styling.

• Chromabond Sealer helps anchor dye molecules to the hair’s protein matrix.
• Citric acid lowers surface pH to smooth and close lifted cuticles.
• Ionic sealing adds a protective, moisture-managing layer around strands.
• Clinically validated performance: consumer testing showed high satisfaction for color protection.

What improvements will I notice after using it regularly?

With consistent use, you can expect improved color depth and a more reflective, multidimensional finish. The duo is formulated to address color-induced weakening, leaving hair smoother, softer, and easier to detangle while maintaining tone longevity.

• Enhanced shine and radiance from a smoothed surface.
• Reduced tonal dulling and visible fading for up to 40 washes.
• Improved manageability and reduced breakage from repair-focused proteins.
• Immediate conditioning benefits after the first application.

How should I use the Color Assure system for best results?

Use the system in place of your regular cleansing and conditioning routine: shampoo to cleanse and begin the bonding process, then apply conditioner to seal and hydrate. For maintained results, pair with complementary Nexxus treatments and minimize harsh chemical or thermal stress between salon visits.

• Apply shampoo to wet hair, lather, and rinse; repeat if hair is heavily styled or product-laden.
• Work conditioner through mid-lengths to ends, leave for 1–3 minutes, then rinse thoroughly.
• Use as your regular wash system; follow with heat protection when styling.
• For maximum vibrancy, combine with weekly Nexxus treatments as needed.

Is this gentle enough for frequent use on color-treated hair?

Yes—the formula is designed for color-treated hair and aims to preserve pigment while delivering moisture. It balances cleansing and conditioning to avoid stripping while reinforcing the hair’s structural integrity.

• Balanced surfactant system cleans without aggressive pigment removal.
• Citric acid and protein-based actives support gentle cuticle smoothing.
• Hydration-focused components help reduce friction and breakage.
• Suitable for routine use between salon appointments.

Who this is for: Nexxus Color Assure is intended for anyone with color-treated, highlighted, or chemically processed hair who wants to extend vibrancy and improve surface condition. It’s particularly useful for people who wash regularly, attend events where color brilliance matters, or use heat styling and want to minimize color loss and surface dulling. For customized repair or intensive needs, consider pairing this duo with targeted Nexxus treatments recommended for your level of damage.
