Redken Acidic Color Gloss Shampoo for Color-Treated Hair, 10.1 fl oz — pH-Balanced, Sulfate-Free Shine

Redken Acidic Color Gloss Shampoo is a pH-balanced, sulfate-free shampoo formulated to preserve salon color and add intense, glossy shine to color-treated hair.

Designed to work as part of Redken's Acidic Color Gloss system, this shampoo uses an acidic pH plus amino acids and vitamin E to smooth the hair cuticle, reduce color fading, and boost surface shine. The gentle formulation cleanses without harsh sulfates, making it suitable for chemically colored hair while helping hair appear healthier and more luminous after use. Results reported in testing showed extended vibrancy across washes when paired with matching treatments.

How does this shampoo help keep color looking fresh?

The shampoo's acidic pH helps the cuticle lie flatter, which reduces the microscopic gaps where color can leach out. Amino acids and vitamin E in the formula support surface conditioning so hair reflects light better, preserving vibrancy and gloss between salon visits.

• pH-balanced formulation seals the cuticle to reduce color loss
• Amino acids provide surface conditioning for smoother strands
• Vitamin E supports antioxidant protection for color longevity
• Recommended to use with Acidic Color Gloss Conditioner and Glass Gloss Treatment for optimal results

Will it clean my hair without stripping color?

Yes—this shampoo is sulfate-free and designed to remove oils and buildup while being milder on colored hair than traditional sulfated cleansers. It delivers a gentle cleanse that helps maintain dye molecules on the fiber rather than washing them away.

• Sulfate-free surfactants cleanse without aggressive stripping
• Removes residues that dull shine while protecting pigment retention
• Safe for regular use as part of a color-care routine

How much extra shine and protection can I expect?

When used with Redken’s complementary glass gloss treatment, the system produces measurable improvements in surface shine compared with unwashed, color-treated hair. The acidic formula helps produce a smoother, more reflective hair surface, which translates to a visibly glossier finish.

• Visible increase in molecular-level shine when used in the recommended system
• Cuticle sealing contributes to a sleeker, light-reflective surface
• Provides conditioning to reduce the roughness that dulls color

How should I use it for best results?

Apply to wet hair, lather gently, and rinse thoroughly; repeat if needed. For maximum color preservation and shine, follow with Redken Acidic Color Gloss Conditioner and consider occasional use of the Glass Gloss Treatment.

• Work through damp hair and massage into the scalp and lengths
• Pair with the Acidic Color Gloss conditioner for balanced hydration
• Use the Glass Gloss Treatment periodically for enhanced shine boost

Who is this for: Redken Acidic Color Gloss Shampoo is formulated for anyone with color-treated or highlighted hair who wants a gentler cleanse and improved surface shine without sulfates. It suits salon-colored, at-home dyed, and chemically processed hair types seeking to extend color vibrancy and a glossy finish between salon appointments. If you prefer milder, pH-aware care that pairs with targeted color-maintenance treatments, this shampoo is a practical choice.
