Nexxus Color Assure Shampoo & Conditioner for Color-Treated Hair, 13.5 oz Duo — Sulfate-Free, Protein Infusion

Nexxus Color Assure Shampoo and Conditioner is a two-step color-care system formulated with elastin protein and quinoa to help maintain vibrant, healthy-looking color for up to 40 washes.

Designed for color-treated hair, this sulfate-free shampoo plus matching conditioner replaces amino acids and fortifies hair fibers after salon services. The formula’s PROTEINFUSION BLEND rebuilds and seals the hair surface while adding moisture so dyed hair looks shinier and feels smoother between color appointments. Use the shampoo to cleanse gently and the conditioner to detangle and lock in vibrancy.

How does this pair protect color-treated hair?

The system works in two complementary steps: the sulfate-free shampoo cleans without harsh stripping, and the conditioner deposits proteins and moisturizers that shield hair from fading. Together they create a barrier that helps reduce color loss from washing and everyday environmental stressors.

• Sulfate-free cleansing to minimize pigment stripping
• PROTEINFUSION BLEND with elastin protein and quinoa rebuilds hair structure
• Moisturizing conditioner smooths cuticles to lock in shine
• Formulated to support color vibrancy for up to 40 washes

What results can I expect after regular use?

With consistent use, hair appears more vibrant and retains salon color longer while feeling softer to the touch. The amino-acid rich blend targets weakened areas of the strand so hair looks healthier and less dull between color services.

• Increased shine and smoother texture
• Reduced brassiness and faded tones over multiple washes
• Improved manageability and reduced tangling

How should I use the Nexxus Color Assure Shampoo and Conditioner?

Start by wetting hair thoroughly and apply the sulfate-free Color Assure Shampoo, massaging gently to lift dirt and styling residues. Rinse and follow with the Color Assure Conditioner, leaving it in briefly to allow proteins and moisturizers to penetrate before rinsing for best results.

• STEP 1: Apply Color Assure Sulfate-Free Shampoo, lather, and rinse
• STEP 2: Apply Color Assure Conditioner or a deep moisture masque, leave for 1–3 minutes, then rinse
• Use regularly as your color-care wash routine; reduce styling heat to extend results

Which ingredients make this duo effective for colored hair?

The formula centers on Nexxus’s PROTEINFUSION BLEND featuring elastin protein and quinoa, plus amino acids that hair loses during coloring. These actives support fiber strength, help rebuild the outer layers of the strand, and provide moisture to prevent dullness.

• Elastin protein to improve elasticity and resilience
• Quinoa-derived extracts for nourishing amino acids
• Moisturizing agents to smooth cuticles and enhance shine

Who is this for: Nexxus Color Assure Shampoo and Conditioner is made for people with dyed or chemically treated hair who want to prolong salon color, restore softness, and reduce the dulling effects of washing and daily wear. It’s a practical choice for anyone looking for a professional-strength, protein-focused routine that supports hair integrity while keeping color vibrant between salon visits.
