The Redken Acidic Color Gloss Litre Duo is the professional 1-litre shampoo and conditioner for colour-treated and bleached hair — using an acidic gloss system that smooths and seals the cuticle with every wash to deliver the mirror-finish shine that colour-treated hair loses when the cuticle lifts, paired with Acidic Bonding technology that protects bond integrity, at Canada's lowest price.
What's Included
• Redken Acidic Color Gloss Shampoo — 1 litre (1000ml)
• Redken Acidic Color Gloss Conditioner — 1 litre (1000ml)
Why Buy the Litre Size
• Save 35% vs buying two regular bottles — glass-finish shine is a daily result that requires a consistent foundation
• Combine with Redken Acidic Bonding Concentrate Leave-In for a complete acid-chemistry colour and shine system
• 1000ml vs 900ml from three regular bottles — 100ml extra free every purchase
• Professional salon size not available at Sephora — Zennkai is one of the few authorized Canadian sources
• Lasts approximately 3–4 months with daily use for medium-length hair
About Redken Acidic Color Gloss
Redken Acidic Color Gloss sits within the Acidic Bonding family but is specifically engineered for the client who prioritises shine alongside bond protection. The acidic formula seals the cuticle to a flat, reflective state that allows light to bounce evenly — the mechanism behind true glass-finish shine. Combined with bond-protecting technology, it addresses both the structural integrity and the surface optical quality of colour-treated and bleached hair.
Key Ingredient
Acidic gloss system — a low-pH formula that flattens the cuticle to a closed, reflective position with every wash, maximizing light reflection for glass-finish shine. Acidic Bonding technology simultaneously seals broken bonds to protect colour integrity and reduce breakage.
Best For
• Colour-treated or bleached hair wanting glass-finish shine
• Hair that looks dull or lacks vibrancy between colour appointments
• Blonde and highlighted hair where gloss and shine are a priority alongside colour protection
• Clients combining a shine-focused routine with daily bond maintenance
• Fine or medium hair where surface reflectivity is visually most impactful
