The Davines OI Litre Duo is the professional-size version of the most universally loved system in the Davines range — a Roucou oil-based shampoo and conditioner that delivers extraordinary softness, luminous shine, and frizz control for every hair type, from a B Corp certified Italian brand that sources its ingredients through regenerative organic agriculture, in the 1-litre professional size at Zennkai's lowest Canadian price.
What's Included
• Davines OI Shampoo — 1 litre (1000ml)
• Davines OI Conditioner — 1 litre (1000ml)
Why Buy the Litre Size
• Significant savings vs buying two regular-size Davines OI bottles — the same B Corp certified formula at the best per-wash value available in Canada
• Davines OI is universally recommended — it works on every hair type without exception, making the litre the smart purchase for anyone who's found their formula
• Not available at Sephora — Davines is a salon-exclusive brand. Zennkai is one of the few authorized Canadian online sources carrying the full litre range
• Buying larger sizes reduces packaging waste — aligned with Davines' sustainability philosophy
• Lasts approximately 4–6 months for medium-length hair — exceptional value for a premium Italian professional brand
About Davines OI
Davines OI is the brand's signature 'all-in-one' system — designed to work beautifully on every hair type, every texture, every concern. The secret is Roucou oil, extracted from the seeds of the Bixa orellana plant and rich in beta-carotene, antioxidants, and essential fatty acids that penetrate the hair shaft to nourish from within. Unlike many professional shampoos that rely on silicones for surface-level softness, OI delivers genuine structural nourishment. Davines is a certified B Corporation — one of very few professional hair care brands in Canada to hold this credential — meaning every ingredient is sourced responsibly, every product is made using renewable energy, and every bottle is recyclable.
Key Ingredient
Roucou oil (Bixa orellana seed oil) — a high-beta-carotene, antioxidant-rich oil sourced by Davines through their regenerative agriculture supply chain. Beta-carotene is a precursor to Vitamin A, which nourishes the hair fibre and supports the scalp's natural sebum balance. The antioxidants in Roucou oil also protect hair from environmental stress and free radical damage.
Best For
• All hair types — OI genuinely performs across straight, wavy, curly, fine, thick, colour-treated, and natural hair
• Dry or dull hair needing everyday nourishment and shine
• Frizzy hair — OI delivers consistent frizz reduction, particularly effective in Metro Vancouver's humid coastal climate
• Sustainability-minded buyers — Davines is B Corp certified with regenerative sourcing and renewable energy production
• Anyone who has tried OI in regular size and wants the best-value professional size
