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

Redken Acidic Color Gloss Sulfate-Free Shampoo is a pH-balanced cleanser designed to extend salon color vibrancy and deliver high-gloss radiance for color-treated hair.

Formulated to work gently on dyed hair, this sulfate-free shampoo uses an acidic pH alongside amino acids and vitamin E to help smooth the cuticle, reduce color fade from water and heat exposure, and visibly amplify shine. When used as part of the Acidic Color Gloss system, Redken reports longer-lasting vibrancy and up to 76% more shine in combination with the Glass Gloss Treatment. The formula cleans without stripping, leaving hair soft, detangled, and refreshed after each wash.

How does this shampoo protect my salon color during regular washes?

The low-pH formula helps the hair cuticle lie flatter, which minimizes color loss and reduces the rate at which pigments escape. By avoiding harsh sulfates, the shampoo cleans without aggressively opening the cuticle, preserving color molecules and vibrancy over time.

• Acidic pH helps seal the cuticle to limit pigment loss
• Sulfate-free surfactants provide a gentler cleansing action
• Amino acids support hair structure for more even color retention

Will this shampoo make my hair look shinier right away?

Yes—ingredients focused on cuticle smoothing and surface light reflection are designed to increase visible shine from the first few uses. When paired with Redken’s Glass Gloss Treatment, the system can significantly enhance gloss for a salon-like finish.

• Cuticle smoothing locks in reflected light
• Vitamin E contributes to a healthier-looking surface sheen
• Works fast: noticeable shine after initial applications

Is this safe for all types of color-treated hair and styling routines?

The shampoo is formulated for use on color-treated hair, including permanent, demi, and semi-permanent shades. Its gentle, sulfate-free base supports frequent washing and plays well with heat styling and common color-safe products, though results depend on individual hair porosity and color technique.

• Suitable for various dyed hair types and tones
• Gentle enough for routine use without harsh stripping
• Complements conditioners and in-salon gloss treatments for best results

How should I incorporate this shampoo into my color-care routine?

Use it in place of your regular shampoo on wash days, focusing on the scalp and roots while letting the lather rinse through lengths. For maximum vibrancy and shine, pair with the matching Acidic Color Gloss Conditioner and occasional Glass Gloss Treatment as part of a complete maintenance system.

• Apply to wet hair, lather, and rinse thoroughly
• Follow with Acidic Color Gloss Conditioner for balanced moisture
• Use Glass Gloss Treatment periodically for peak shine and long-term color boost

Who this is for: Redken Acidic Color Gloss Shampoo is ideal for anyone with professionally or at-home color-treated hair who wants a gentler wash that helps maintain hue and adds noticeable shine. It suits busy people who wash regularly but still need to protect dye longevity, as well as salon clients seeking a take-home product to extend in-chair results without heavy buildup or stripping surfactants.
