The Redken Volume Injection Litre Duo is the professional 1-litre shampoo and conditioner for fine, flat, or limp hair — collagen-infused to lift each strand at the root, build body through the mid-lengths, and deliver lasting volume without weighing fine hair down, in the professional salon size at Canada's lowest price.
What's Included
• Redken Volume Injection Shampoo — 1 litre (1000ml)
• Redken Volume Injection Conditioner — 1 litre (1000ml)
Why Buy the Litre Size
• Save 35% vs buying two regular-size bottles — same collagen-infused formula at the best per-wash value in Canada
• Fine hair typically uses less product per wash — a litre lasts proportionally longer than for thick hair, making it exceptional value
• Professional salon size not available at Sephora — Zennkai is one of the few authorized Canadian sources for Redken litre sizes
• Lasts approximately 4–6 months for fine, medium-length hair with daily use
• Same concentrated professional formula as salon — collagen at professional strength, not a diluted consumer version
About Redken Volume Injection
Redken Volume Injection is designed specifically for fine, flat hair that needs sustainable body and lift — not the stiff or crunchy volume delivered by heavy stylers. The collagen-infused formula works inside the strand to strengthen fine hair fiber and improve resilience, so volume comes from structural improvement rather than surface buildup that weighs hair back down by midday.
Key Ingredient
Collagen — a protein that fills and reinforces fine hair fiber from within, adding body and structural integrity without weight. Works inside the strand rather than coating the surface, delivering lift at the root and through the mid-lengths with no residue that causes fine hair to flatten faster.
Best For
• Fine, flat, or limp hair lacking body and lift
• Hair that goes flat quickly after washing or styling
• Fine hair needing volume without weight or buildup
• Colour-treated fine hair needing volume without compromising colour longevity
• Anyone who wants professional salon volume results from their daily shampoo and conditioner
