For some va-va-volume, spray a bit of this bodifying mist onto your roots, massage into your scalp, and brush out any excess. Formulated with oil-absorbing silica and hydrating argan oil, it zaps grease where needed and polishes the rest. Go ahead now: Hit the gym before work like you said you would.
