Redken Acidic Color Gloss Shampoo — Sulfate-Free Color Care, pH-Balanced Shine for Color-Treated Hair

Redken Acidic Color Gloss Shampoo is a pH-balanced, sulfate-free formula that seals the cuticle and boosts salon-grade shine for color-treated or dull hair.

This shampoo is designed to preserve salon color and add noticeable gloss without harsh detergents. Formulated with an acidic pH plus amino acids and vitamin E, it smooths the hair surface to reflect light and help reduce color dulling from water and heat. When used as a system with Redken's complementary treatments, it supports prolonged vibrancy and visibly shinier hair.

How does the acidic formula help my color last longer?

An acidic pH helps the hair cuticle lie flatter, which slows color molecules from escaping and reduces surface roughness that scatters light. Redken combines this pH balance with conditioning agents so hair feels smoother after cleansing. In clinical comparisons, the system supported longer-lasting color for up to 32 washes when paired with the matching conditioner.

• pH-balanced to close the cuticle and reduce color fade
• Contains amino acids and vitamin E to condition while cleansing
• System-tested to extend salon color for up to 32 washes

Will this shampoo actually increase shine?

Yes—the formula focuses on molecular-level smoothing so more light reflects off the hair shaft. Used with Redken Glass Gloss Treatment, the regimen produced up to 76% shinier hair versus unwashed color-treated hair in lab comparisons. The result is a surface that looks glossier and feels smoother without heavy residue.

• Seals cuticle for a smoother surface and higher light reflection
• Proven shine boost when paired with Glass Gloss Treatment
• Lightweight finish preserves movement and avoids buildup

Is this gentle enough for daily use and color care?

The sulfate-free cleansing base removes impurities while avoiding strong surfactants that can strip dye. Its gentle action helps protect color vibrancy and maintain moisture balance, making it suitable for regular use based on hair needs. As with any color-care routine, pairing with the matching conditioner or gloss treatment improves results.

• Sulfate-free formula for a milder cleanse
• Helps retain moisture and color without aggressive stripping
• Best used as part of the Acidic Color Gloss system for full benefits

How should I incorporate it into my hair routine?

Apply to wet hair, lather gently, then rinse and follow with the Acidic Color Gloss Conditioner or Glass Gloss Treatment for maximum color and shine preservation. Frequency depends on how often you wash; people with color-treated hair often alternate with a mild clarifying or moisturizing shampoo. For targeted shine, add the Glass Gloss Treatment occasionally for a concentrated sheen boost.

• Use on wet hair, lather, rinse, then condition
• Pair with Redken Acidic Color Gloss Conditioner or Glass Gloss Treatment
• Adjust wash frequency to hair type and color-maintenance needs

Who is this for: Redken Acidic Color Gloss Shampoo is aimed at anyone with color-treated, highlighted, or dull hair who wants a gentler cleanse that preserves salon color and increases surface shine. It’s suited to those seeking a sulfate-free option that works best when combined with complementary Redken glossing products for extended vibrancy and a polished finish.
