Feel like you're strands need a pick-me-up, but you're running short on time? As long as you've got one of these great dry shampoos on hand, you're good to go. Simply spray on your roots and brush through, and give dirty dulled hair an uplifting experience. Though it doesn't replace that fresh, just out of the shower look and feel, it's an easy way to cheat when you're in a hurry. We love Got2b Fat-Tastic Fresh & Full Dry Shampoo ($5.99 at Drugstore.com), Ojon Full Detox Rub-Out Dry Cleansing Spray ($24 at Sephora.com) and Serge Normant Meta Revive Dry Shampoo ($25 at Barneys.com).
