The Biolage Volume Boost Litre Duo is the professional 1-litre shampoo and conditioner for fine, limp, or flat hair — inspired by cotton's lightweight strength and formulated to build body and lift at the root while maintaining the featherweight feel that keeps fine hair bouncy and lifted throughout the day, at Canada's lowest price.
Â
What's Included
•       Biolage Volume Boost Shampoo — 1 litre (1000ml)
•       Biolage Volume Boost Conditioner — 1 litre (1000ml)
Â
Why Buy the Litre Size
•       Save 38% vs buying two regular-size bottles — excellent value volume system at one of the most accessible professional price points at Zennkai
•       Fine hair uses less product per wash — a litre lasts proportionally longer than for thick hair
•       Not available at Sephora in litre size — professional salon-channel exclusive at Zennkai
•       1000ml vs 900ml from three regular bottles — 100ml extra free every purchase
•       Lasts approximately 4–6 months for fine, medium-length hair with daily use
Â
About Biolage Volume Boost
Biolage Volume Boost draws on cotton's structural paradox — extraordinarily lightweight but genuinely strong. The formula builds body and lift in fine hair from inside the strand rather than coating it with heavy volumizing agents that create initial lift but cause buildup and faster flatness over time. Particularly effective for fine hair that needs volume at the root without compromise to texture or movement.
Â
Key Ingredient
Cotton-inspired volume complex — botanical actives drawn from cotton's featherweight strength that build body inside the fine hair fiber without surface buildup. Lightweight volumising formula — free from the heavier conditioning agents that flatten fine hair while still providing enough smoothness for manageable, shiny results.
Â
Best For
•       Fine, flat, or limp hair lacking volume and body
•       Hair that goes flat quickly after styling
•       Fine hair that wants professional volume without buildup
•       Clients who find most conditioners too heavy and compromising to volume
•       Fine hair at any age needing daily body and lift
