Nexxus Color Assure Shampoo & Conditioner for Color-Treated Hair, 13.5oz 2-Pack, Sulfate-Free

Nexxus Color Assure Shampoo and Conditioner is a two-step salon-formulated system that cleanses, replenishes protein, and helps maintain hair color vibrancy for up to 40 washes.

Color-treated hair loses amino acids and moisture during dyeing and routine styling; this Nexxus duo combines a sulfate-free cleansing shampoo and a protein-rich conditioner designed to restore those lost nutrients. Formulated with the PROTEINFUSION BLEND—featuring elastin protein, quinoa, and targeted amino acids—the pair works to strengthen hair fibers, reduce dullness, and help keep color looking fresh between salon visits. Use the shampoo first to remove impurities while protecting pigments, then follow with the conditioner to seal and hydrate strands.

How does this system preserve color for weeks?

The formula minimizes pigment fade by cleansing gently and replenishing structural proteins that support cuticle integrity, which helps lock color in place. It avoids harsh surfactants that strip dye, while the conditioner restores moisture and smooths the hair surface.

• Sulfate-free shampoo to reduce aggressive color stripping
• Elastin protein and quinoa to rebuild weakened fiber
• Amino acids to support color retention and shine
• Works on many dye types: permanent, demi, and semi-permanent

What results can I expect after using it regularly?

Expect improved manageability, softer texture, and a more vibrant appearance through daily styling and multiple washes. Over time, hair tends to feel stronger and look glossier as the protein blend replenishes what coloring removed.

• Visible color vibrancy for up to about 40 washes with regular use
• Reduced dryness and frizz when paired with the conditioner
• Smoother, more resilient hair shaft appearance
• Better detangling and easier styling after conditioning

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

Use the sulfate-free Color Assure Shampoo first to cleanse scalp and strands, then rinse thoroughly. Apply the Color Assure Conditioner focusing on mid-lengths to ends; leave for a minute or two and rinse for best results. For an extra boost, substitute or follow with the Color Assure Deep Moisture Masque weekly.

• Wet hair, lather shampoo, massage scalp, rinse completely
• Apply conditioner from mid-shaft to ends, leave briefly, rinse
• Use masque weekly for deeper protein and moisture replenishment
• Pair with heat protection for styling to prolong color life

Is this safe for all color-treated hair types?

The system is designed for a wide range of colored hair types, including highlighted, all-over color, and chemically-treated textures. While formulated to be gentle and restorative, individual needs (very fine, very porous, or highly damaged hair) may require adjustments in frequency or additional moisturizing treatments.

• Works on straight, wavy, curly, and coily textures
• Suitable for highlighted, balayage, and full-color services
• Great as a maintenance system after salon color services
• Heavily damaged hair may benefit from periodic deep masks

Who is this for: Nexxus Color Assure Shampoo and Conditioner is ideal for anyone who dyes their hair and wants to extend vibrancy, improve manageability, and rebuild proteins lost during coloring. It fits customers seeking salon-grade, protein-focused care without harsh sulfates—people aiming to maintain their color between salon appointments while keeping strands soft and resilient.
