Spending an evening at home to “wash your hair” is a long-gone tradition. However, the need for hair that looks freshly washed is a constant. Enter L’Oréal Professionnel Fresh Dust — a spray-on, leave-in dry shampoo that disappears in all hair colors. The microfine powder absorbs excess oil and refreshes hair while injecting volume. The result is hair that feels soft and clean with a fresh scent. $19 for a travel-friendly 3.4-ounce can, www.lpsalons.com
