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

Redken Acidic Color Gloss Shampoo is a pH-balanced, sulfate-free cleanser that helps preserve salon color and deliver noticeable shine for color-treated hair.

Formulated specifically for color-treated hair, this shampoo uses an acidic pH plus amino acids and vitamin E to help close the cuticle and lock in vibrancy. Designed to work as part of the Acidic Color Gloss system, it offers a gentle cleanse while concentrating on color protection and molecular-level shine without harsh sulfates. The result is revitalized-looking hair that feels smoother and appears glossier between salon visits.

How does this shampoo help slow color fading?

The low (acidic) pH helps the hair cuticle lie flatter after cleansing, which reduces color stripping from water, washing, and heat exposure. The formula is sulfate-free so it cleans without aggressively stripping dye molecules. Used with the matching conditioner or glass gloss treatment, it extends visible vibrancy for more washes than ordinary shampoos.

• pH-balanced, acidifying formula to help seal the cuticle
• Sulfate-free surfactants for a gentler wash
• Best results when paired with Acidic Color Gloss conditioner or Glass Gloss Treatment
• Clinical system data: extended vibrancy up to 32 washes*

What active ingredients are included and what do they do?

Key actives are amino acids and vitamin E, chosen to support the hair surface and add antioxidant support. Amino acids assist in smoothing the cuticle while vitamin E helps condition the hair fiber. Together they boost manageability and contribute to the shampoo’s shine-enhancing effect.

• Amino acids: help smooth and support the cuticle
• Vitamin E: conditioning and hair fiber support
• Acidic formulation: helps seal and reflect light for glossy results

How shiny and noticeable is the result?

The Acidic Color Gloss system is designed for molecular-level shine; laboratory comparisons show substantially increased gloss when the shampoo is combined with the Glass Gloss Treatment. Visually, hair appears sleeker and reflects more light, improving the look of color intensity and depth.

• Claims of up to +76% shinier hair with Shampoo + Glass Gloss Treatment vs. unwashed color-treated hair
• Smoother cuticle for higher light reflection
• Instant aesthetic improvement after first use

Is this shampoo gentle enough for frequent use?

Yes. The sulfate-free formulation provides a milder cleanse suited to regular use on color-treated hair. Because it helps maintain cuticle integrity and uses gentle surfactants, you can incorporate it into your routine to help prolong salon color between appointments.

• Sulfate-free for less aggressive cleansing
• Formulated to support repeated use on dyed hair
• Pairs with conditioner/treatment for optimal protection

Who is this for: Redken Acidic Color Gloss Shampoo is intended for anyone with color-treated or highlighted hair who wants a gentler wash that focuses on preserving salon color and boosting shine. It’s a practical choice for people aiming to stretch time between color appointments while keeping hair looking glossy and refreshed. For best results, use within the Acidic Color Gloss system (shampoo, conditioner, and optional Glass Gloss Treatment).
