Bigger, better, full-on glamorous hair. This invisible dry hair spray builds in incredible volume and sultry texture. Zeolite crystallines absorb oil at the roots, leaving you with just-styled hair for days (and nights). HOW TO USE Shake. Spray where you want volume. Style to desired finish and hold. A brilliant alternative to dry shampoo. To break the safety seal upon first use, remove the cap, place your thumb on the back of the applicator, and press firmly until it audibly clicks.
