Nexxus Color Assure Sulfate-Free Shampoo for Color-Treated Hair 3 oz — ProteinFusion for Vibrancy

This sulfate- and silicone-free shampoo uses Nexxus' PROTEINFUSION blend—featuring Elastin Protein and Quinoa—to support color-treated strands after the chemical stresses of coloring. Formulated to gently lift oils, product buildup, and environmental grime without stripping pigment, it’s designed as part of a color-care routine that helps hair look brighter and feel more resilient between salon visits.

How does this shampoo protect color on wash days?

The formula avoids harsh sulfates and silicones that can prematurely fade hair color, instead relying on a protein-rich blend that helps reinforce the hair surface and maintain vibrancy. Regular use as part of a matching regimen contributes to extended color life.

• Sulfate-free cleansing to reduce pigment loss during washing.
• PROTEINFUSION with Elastin Protein and Quinoa to support strand integrity.
• Gentle surfactants that remove buildup without aggressive stripping.
• Designed to pair with the Color Assure conditioner for best results.

Will this work on my specific color type—brunette, red, or blonde?

The shampoo is formulated for all types of color-treated hair and is safe to use on brunette, red, blonde, and highlighted shades. While it helps maintain overall vibrancy, color longevity can also depend on your dye type, water quality, and styling routine.

• Safe for permanent and semi-permanent colored hair.
• Suitable for both single-process and highlighted/bleached hair.
• Use with complementary Color Assure products for targeted care (e.g., purple shampoo for blondes).
• Helps preserve surface shine so color appears more vivid.

How should I use this shampoo for best results?

Apply a small amount to wet hair, lather gently from roots to ends, then rinse thoroughly; follow with Nexxus Color Assure Long Lasting Vibrancy Conditioner. For maximum color preservation, wash less frequently, use lukewarm water, and limit heat styling when possible.

• Use 2–3 times per week for maintenance; adjust based on oiliness and activity level.
• Pair with matching conditioner and occasional masque treatments for deeper repair.
• Rinse with cool water to help seal the cuticle and lock in shine.
• For blonde or silver tones, alternate with the purple Color Assure shampoo as directed.

Whether you’re preserving a vibrant red, a rich brunette, or a multidimensional blonde, this 3 oz size is convenient for travel, trialing the line, or keeping in a gym bag as part of a color-care routine.
