Nexxus Color Assure Shampoo & Conditioner for Color-Treated Hair, 13.5 oz Each — Sulfate-Free, Protects Color Up to 40 Washes

Nexxus Color Assure Shampoo and Conditioner is a two-step system that cleanses, nourishes and helps preserve salon color vibrancy for up to 40 washes.

Formulated with the brand's PROTEINFUSION BLEND—featuring elastin protein, quinoa and amino acids—this sulfate-free shampoo and matching conditioner are designed specifically for color-treated hair. The pairing replenishes nutrients lost during coloring while smoothing and moisturizing the hair fiber so color looks brighter and hair feels healthier between salon visits. Use the shampoo to gently cleanse and boost color, then follow with the conditioner to seal moisture and protect the hair shaft.

How does this system protect dyed hair without stripping color?

The sulfate-free shampoo uses gentle surfactants and a protein-focused formula to remove dirt and product buildup without aggressively washing out pigments. The conditioner restores lipids and amino acids to the hair fiber, reducing porosity so color molecules are held more securely.

• PROTEINFUSION BLEND with elastin protein and quinoa for structural support
• Sulfate-free cleansing to minimize pigment fade
• Conditioner adds moisture and reduces color-leaching porosity

What results can I expect and for how long?

With consistent use, the system is formulated to help maintain color vibrancy for up to 40 washes while improving texture and shine. Users typically notice softer, more manageable hair and clearer color tone retention between color appointments.

• Up to 40 washes of enhanced color vibrancy as formulated
• Smoother, less brittle hair after conditioning
• Improved shine and manageability for everyday styling

How should I use the shampoo and conditioner for best effect?

Apply the sulfate-free Color Assure Shampoo to wet hair, lather, and rinse thoroughly to remove residues while reinforcing color. Follow with the Color Assure Conditioner, leave in for one to two minutes, then rinse; for deeper repair, alternate with Nexxus Color Assure Deep Moisture Masque.

• Step 1: Shampoo to cleanse and enhance pigment vibrancy
• Step 2: Condition to replenish proteins and seal the cuticle
• Optional: Use Deep Moisture Masque periodically for intensive nourishment

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

The formulation is suitable for a broad range of color-treated hair, including permanent, demi-permanent and highlights. It is designed to restore amino acids and strengthen the hair regardless of texture, though results vary depending on prior chemical services and hair health.

• Works on permanent and semi-permanent color services
• Beneficial for highlighted, lowlighted and all-over color
• Compatible with varied hair textures—fine to coily—when used as directed

Who is this for: Nexxus Color Assure Shampoo and Conditioner is aimed at anyone who colors their hair and wants salon-quality maintenance at home. It's ideal for people seeking a protein-rich, sulfate-free routine to protect color tone, enhance shine and improve hair strength between salon visits—suitable for most color types and hair textures when used consistently.
