The Biolage Smoothproof Litre Duo is the professional 1-litre shampoo and conditioner for frizzy, unruly, or rebellious hair — inspired by the camellia plant's extraordinary smoothing and moisturising properties, formulated to seal the cuticle, reduce frizz for up to 6 days, and provide the softness and manageability that combats Metro Vancouver's coastal humidity from the first wash, at Canada's lowest price.
What's Included
• Biolage Smoothproof Shampoo — 1 litre (1000ml)
• Biolage Smoothproof Conditioner — 1 litre (1000ml)
Why Buy the Litre Size
• Save 38% vs buying two regular-size bottles — excellent frizz control value for daily use in Vancouver's coastal climate
• Metro Vancouver's coastal humidity makes anti-frizz products a daily necessity — the litre supports that consistent daily use
• 1000ml vs 900ml from three regular bottles — 100ml extra free every purchase

• Lasts approximately 3–4 months with daily use for medium-length hair
About Biolage Smoothproof
Biolage Smoothproof is inspired by the camellia, a plant whose leaves are renowned for their extraordinary smoothness and resistance to environmental moisture — the botanical parallel to what anti-frizz hair care aims to achieve. The shampoo and conditioner together seal the cuticle and deposit smoothing actives that build a humidity-resistant surface, reducing frizz for up to 6 days with consistent use. In Metro Vancouver's high-humidity coastal climate, Smoothproof provides the daily cuticle-sealing foundation that keeps frizz manageable regardless of weather.
Key Ingredient
Camellia-inspired smoothing complex — botanical actives drawn from the camellia plant's surface properties, formulated to seal the hair cuticle and build a humidity-resistant smoothing layer. Anti-frizz conditioning system — a blend of smoothing emollients that soften and control unruly texture without weighing hair down.
Best For
• Frizzy, unruly, or rebellious hair in Metro Vancouver's coastal climate
• Hair that puffs or loses definition in humidity
• Thick, coarse, or wavy hair prone to frizz
• Colour-treated frizzy hair — Smoothproof is colour-safe
• Clients looking for a professional anti-frizz system at an accessible price point
