People who want lift and volume concentrated at the roots without weighing down their lengths – useful for fine or fine-to-medium hair that goes flat, but Redken markets it across all hair types including coarse, color-treated, and natural hair. It's suited to at-home or salon blow-dry styling, for men and women.

The main thing that differentiates this from a full-head volumizing mousse is that it's built to be dispensed and worked in section by section right at the root, so you get lift where hair tends to go flat without adding weight or stiffness through the mid-lengths and ends – something a lot of all-over sprays and mousses don't do as precisely.

Shake the can well, then apply to towel-dried hair section by section, working the foam into the roots and lifting each section as it's applied. Finish by blow-drying with a round brush to set the lift and volume.

Pros: it lets you target lift right at the root instead of adding bulk throughout, so fine hair doesn't get weighed down; it's formulated for a range of hair types including color-treated hair; medium control means it's buildable rather than instantly stiff. Cons: like most aerosol root-lifters it depends on a round-brush blow-dry to actually show its lift – air-drying after application won't do much; it's a fragranced aerosol formula (contains hexyl cinnamal, linalool as scent components), so it's not fragrance-free; and it's a medium-control product, so it isn't meant to hold through humidity or long days the way a firmer-hold spray would.
