Redken Acidic Color Gloss Sulfate-Free Shampoo for Color-Treated Hair — pH-Balanced, Shine-Boosting (8.5 fl oz)

Redken Acidic Color Gloss Sulfate-Free Shampoo is a pH-balanced shampoo designed to extend salon color and deliver intense, glossy shine for color-treated hair.

This gentle, sulfate-free formula uses an acidic pH plus amino acids and vitamin E to help smooth the cuticle, preserve pigment, and refresh color vibrancy between salon visits. Formulated specifically for color-treated hair, the system shows measurable improvements in shine when paired with complementary Redken treatments. The shampoo cleanses without stripping, leaving hair feeling soft and looking radiant while helping protect against dulling from water and heat exposure.

How does this shampoo help keep color vivid?

The acidic formula helps close the hair cuticle after cleansing so color pigments are retained longer. By preventing premature pigment loss and smoothing the surface, hair reflects light better, which preserves perceived richness of color. Regular use in a color-care routine slows color dulling between color appointments.

• pH-balanced, acidic formula to seal the cuticle
• Amino acids and vitamin E support color stability
• Sulfate-free cleansing to avoid harsh pigment stripping
• Formulated to pair with Redken gloss treatments for extended results

Will it actually increase shine and how noticeable is the effect?

Yes — the formula is engineered to produce molecular-level shine by smoothing cuticle layers so light reflects more evenly. In controlled use with Redken glass gloss treatments, users reported a substantial shine increase versus unwashed color-treated hair. Expect a glossy, salon-finished look without heavy residue.

• Seals cuticles to boost reflectivity
• Lightweight conditioning prevents dull buildup
• Compatible with gloss treatments for amplified results

Is this shampoo safe for my color-treated hair and how often should I use it?

The sulfate-free, pH-balanced composition is formulated specifically for color-treated hair and cleanses gently without accelerating fade.

How does it fit into my existing hair routine?

Introduce Acidic Color Gloss as your primary shampoo for color-treated hair and follow with the matching conditioner or a glossing treatment for best results.

Use alongside occasional salon glosses to extend the intervals between color appointments.

• Follow with Redken Acidic Color Gloss Conditioner or a glass gloss treatment
• Complement with heat protectant and minimal color-stripping styling products
