Redken Acidic Color Gloss Shampoo — Sulfate-Free Color Care, pH-Balanced Shine Enhancer (8.5 oz)

Redken Acidic Color Gloss Shampoo is a pH-balanced, sulfate-free shampoo made to extend salon color vibrancy while sealing the hair cuticle for amplified shine.

This shampoo pairs gentle cleansing with an acidic formula that helps compress the cuticle and preserve salon-applied color. Formulated with amino acids and vitamin E, it aims to reduce the hair surface roughness that makes color look dull and helps hair reflect light more evenly. Use it as part of a color-care routine to maintain a refreshed, glossy finish between salon visits.

How does this shampoo protect and prolong color?

The acidic pH helps smooth and flatten the cuticle layer, which reduces color stripping from water and styling. Combined with conditioning agents, the formula helps hair retain pigments longer and keeps tones looking true.

• pH-balanced formula designed to close the cuticle after cleansing
• Sulfate-free surfactants for a gentler wash that preserves dye molecules
• Contains amino acids and vitamin E to support hair surface integrity
• When used with the matching system, can help maintain color vibrancy across multiple washes

Will this shampoo actually make hair shinier?

The product targets molecular-level shine by smoothing the hair’s outer layer so light reflects more uniformly. Clinical comparisons show a notable increase in measured shine when paired with Redken glass gloss treatments versus unwashed color-treated hair.

• Acidic formulation helps compress the cuticle for a smoother finish
• Designed to boost surface-level light reflection for visible gloss
• Works best as part of a system (shampoo + treatment) for maximum shine

How gentle is it for frequent use and sensitive scalps?

Because it is sulfate-free, this shampoo provides a milder cleanse than traditional sulfated shampoos, reducing the likelihood of stripping both color and natural oils. It’s formulated to be suitable for regular use on color-treated hair while delivering conditioning benefits.

• Sulfate-free cleansing agents minimize aggressive stripping
• pH tuning helps reduce cuticle disruption compared with alkaline cleansers
• Conditioning ingredients leave hair manageable after washing

How should I include it in my at-home color-care routine?

Swap your regular shampoo for this acidic gloss shampoo and follow with a complementary conditioner or the Glass Gloss Treatment for best results. Use as often as you normally shampoo, and consider alternating treatments or masks recommended by your stylist.

• Wet hair, lather a small amount, rinse thoroughly; repeat only if needed
• Follow with Redken Acidic Color Gloss Conditioner or a gloss treatment for improved results
• Pair with heat protection when styling to further protect color vibrancy

Who is this for: Redken Acidic Color Gloss Shampoo is designed for anyone with color-treated or chemically enhanced hair who wants a salon-like glossy finish at home. It suits people looking to reduce color fade and boost surface shine without harsh sulfates — ideal for those who shampoo regularly and want manageable, vibrant-looking hair between professional glossing services.
