The Biolage Volume Boost Holiday Duo is a 2026 holiday box with full-size Volume Boost Shampoo and Conditioner, a lightweight volumizing routine for fine, flat hair.
Inside the box:
- Volume Boost Shampoo, 13.5 oz (400 ml)
- Volume Boost Conditioner, 13.5 oz (400 ml)
Both formulas carry Biolage's micro-dosed volume concentrate of soy protein and polymers. The plumping shampoo cleanses fine hair with minimal stripping and gives lift at the root that lasts. The conditioner moisturizes and detangles without weighing strands down, so the volume you built in the wash is still there after rinsing.
Soy protein helps fine hair hold on to moisture and resist brittleness, which keeps it soft and shiny, while the polymers add volume from the roots for natural-looking lift and fullness.
Both products are paraben-free, suitable for colour-treated hair, vegan and certified cruelty-free under the Leaping Bunny Programme, and the shampoo bottle and cap are made with 100% recycled plastic. Boxed for the holidays, the pair makes a simple gift for anyone whose hair goes limp by midday.
