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

Nexxus Color Assure Shampoo and Conditioner is a two-piece color-care system that helps maintain dyed hair vibrancy for up to 40 washes while replenishing proteins lost during coloring.

If you color your hair and want salon-fresh tone between appointments, this duo is formulated to help preserve your shade and the hair’s softness. The pair combines a sulfate-free Color Assure Shampoo and a matching conditioner built around Nexxus’s PROTEINFUSION BLEND — a mix of elastin protein, quinoa, and targeted amino acids — to help restore nutrients stripped during chemical services and daily styling.

How does this system help colored hair stay vibrant?

The formula focuses on replenishing proteins and hydrating strands so color appears fresher and hair looks shinier. Ingredients designed to replace amino acids help strengthen the hair fiber, while conditioning components smooth the cuticle to reduce color-fading factors like friction and dullness.

• PROTEINFUSION BLEND with elastin protein and quinoa to support hair structure
• Hydrating agents that smooth and add shine
• Sulfate-free shampoo option to reduce aggressive stripping of dye
• Conditioner seals the strand to help minimize color loss from washing

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

Use the system in two steps: cleanse first, then condition. Start with the Color Assure Sulfate Free Shampoo to lift impurities without harsh detergents, rinse thoroughly, and follow with the Color Assure Conditioner or an occasional deep moisture masque to fortify and lock in vibrancy.

• STEP 1: Apply shampoo, lather, and rinse; repeat if needed for heavy styling product buildup
• STEP 2: Apply conditioner from mid-length to ends; leave for a few minutes before rinsing
• Optional: Swap in the Deep Moisture Masque weekly for extra protein and hydration
• Use consistently to help maintain color for up to 40 washes

Will this work on different types of color-treated hair?

The system is created to benefit a range of color-treated hair, including single-process, highlights, and chemically lightened hair. By focusing on protein replenishment and cuticle care rather than a single pigment technology, it supports strength and surface smoothness across textures.

• Formulated for chemically colored, highlighted, and tone-treated hair
• Suitable for fine to coarse textures when used according to instructions
• Focuses on structural repair to help hair handle styling and heat
• Complement with salon treatments for highly compromised hair when needed

How long does the color protection last and what affects it?

Nexxus states the system helps maintain color vibrancy for up to 40 washes when used as directed. Actual longevity depends on factors like water hardness, shampoo frequency, heat styling, and exposure to sun or chlorine, all of which influence fade rate.

• Manufacturer guidance: vibrant appearance may last up to 40 washes with regular use
• Reduce wash frequency and use cool rinses to extend color life
• Use UV-protective products and avoid prolonged sun or chlorinated water exposure
• Pair with color-safe styling products to minimize additional fading

Who is this for: Nexxus Color Assure Shampoo and Conditioner is aimed at people who regularly color their hair and want a targeted at-home system to preserve shade, smooth the cuticle, and replenish proteins lost in chemical processing. It suits those seeking salon-quality maintenance between color appointments and anyone wanting to protect the look and feel of treated hair without daily harsh sulfates.
