What Is It?

OLAPLEX No.4FINE and No.5FINE Bond Maintenance Volume and Strength Duo is a shampoo and conditioner system specifically formulated for the needs of fine hair.

OLAPLEX No.5FINE Bond Maintenance Conditioner 250ml

A lightweight volumising conditioner designed to hydrate and nourish fine hair while maintaining lift and movement.

It helps detangle, smooth and condition while supporting lasting body and bounce. OLAPLEX states that it doubles hair volume instantly while helping repair everyday damage.

Together, they create an essential cleanse, strengthen, hydrate and volumise routine specifically for fine hair.
