The grapefruit and oatmeal blend in the Verb Dry Shampoo for Light Hair ($18) and Verb Dry Shampoo for Dark Hair ($18) can preserve blowouts by reducing oil and impurities in the hair, and add volume, too. Both the purple-toned version for blondes and the beige-undertoned option for brunettes are popular with other Sephora shoppers as well.
