Prepare for dramatic effects - and take up space - with volume. This airy hair thickening foam is a hair styling product and scalp treatment that provides an instant increase in visible hair density and instant volume from roots to ends that lasts all day. With Strand Plumping Technology and a blend of peptides and antioxidants that boost energy and protect against external aggressors to create a healthy follicle environment, this heat-protective blowout foam is a must-have for all hair textures and especially for fine hair. How to use: Do not shake the bottle. For extra dramatic styles, apply 3-5 pumps evenly to damp hair from roots to ends. (To use as a scalp treatment, massage 5-10 pumps into the scalp before styling). Blow-dry with a round brush for extra bounce or with a diffuser for full, natural curls and waves.
