Overview

Spritzing through damp waves defines and refines them without weight in this KEVIN.MURPHY enhancer, made for fine hair. It boosts shine and elasticity while cutting frizz for everyday texture.

Definition without heaviness suits fine waves that collapse under gels or creams. Thick or tightly coiled hair may need a stronger styler.

Who it's for

Fine-haired wavy and curly people who want natural, touchable texture get light definition. Those with dense curls may need to layer a heavier product.

Performance notes

Definition comes from a light film that helps waves clump and spring back, adding elasticity rather than stiffness. Frizz drops as strands stay smoother through the day.
