Want another no-shower-required hair cocktail? David has one for you, and all you need is dry shampoo and volumizing hairspray. The dry shampoo will get rid of any oily build-up while the hairspray will add volume root to tip. David recommends Redken’s Powder Refresh 01, $19.95, with his own Angelo David Premier Volume Spray, $18.50.

To begin, spray the dry shampoo at the roots. Don’t be afraid to overuse the product; you want to spray a liberal amount of shampoo. Next, use a paddle brush to massage the dry shampoo into your scalp and distribute it throughout your hair. Finally, spray the volumizing hairspray at your roots for even more lift. No one will guess your hair was dirty just an hour earlier.
