Redken Acidic Color Gloss Sulfate-Free Shampoo 1.7 fl oz — pH-Balanced, Color-Protecting Shine

Redken Acidic Color Gloss Shampoo is a pH-balanced, sulfate-free shampoo designed to prolong salon color and deliver high-shine results for color-treated hair.

Formulated for hair that has been colored, this concentrated 1.7 fl oz shampoo uses an acidic pH plus amino acids and vitamin E to help smooth the cuticle and protect color vibrancy. The formula cleanses gently without sulfates while contributing to measurable shine and protection against fading from water and heat exposure. When paired with complementary Redken treatments, it can extend color longevity and noticeably increase sheen.

How does this shampoo help preserve hair color?

The Acidic Color Gloss Shampoo is formulated to work at an acidic pH that helps the hair cuticle lie flatter, which reduces color washout and surface dulling. It is sulfate-free to minimize aggressive stripping of dye molecules and includes conditioning ingredients to support color longevity.

• pH-balanced formula helps seal the cuticle after coloring
• Sulfate-free surfactants provide a gentler cleanse
• Amino acids and vitamin E help maintain color integrity
• Designed to be used regularly or as part of a color-care system

Will this really make hair shinier?

Yes — the formula is engineered to increase surface reflectivity by smoothing the hair shaft. In Redken testing, using the shampoo together with the Glass Gloss Treatment delivered significantly higher shine compared with unwashed color-treated hair.

• Works at a molecular level to smooth cuticle layers
• Pairs with gloss treatments for maximum shine gains
• Leaves hair feeling glossy, not weighed down

Is the shampoo gentle enough for frequent use?

The sulfate-free composition offers a milder cleaning action than traditional shampoos, making it suitable for regular use on dyed hair. It cleans without harsh stripping, so color and conditioning agents remain more effective between salon visits.

• Gentle cleansing for color-treated strands
• Helps reduce fading from repeated washing
• Neutralizes mineral and environmental dulling factors

How should I use this product for best results?

Apply to wet hair, massage into the scalp and through the lengths, then rinse thoroughly. For optimal color preservation and shine, use with Redken Acidic Color Gloss Conditioner or a Glass Gloss Treatment as part of a complete system.

• Use with matching conditioner or gloss treatment for best effect
• Massage gently to activate smoothing and shine benefits
• Rinse completely and follow with conditioner for balanced moisture
