Living proof Full Dry Volume Blast gives you volume and texture that's almost as light as air for big, lasting results. It's formulated with the brand's new, patent-pending, expendable, textured aero-spheres called ETAS, which deliver big volume and texture on your hair without weighing it down. Fine, flat hair is transformed into voluminous styles without any crunchiness or stiffness.How to use: Shake to activate the formula. ETAS is so lightweight that it floats in the can, so it's important to shake well before each spray. Hold the canister 10" away from your hair. Section hair, then lift and spray roots to ends. Repeat until desired style is achieved, making sure to shake the can between each spray. Tousle hair with your fingers. Spray on finished styles for extra texture and hold.
