Dry shampoo trick

Dry shampoo has been part of my morning—and travel—routine for ages. You don't have to wash your hair every day, and dry shampoo will keep it looking pretty and not greasy, and your hair actually gets easier to style. (In fact, in the photo above, Caroline hadn't washed her hair in three days!)

But here's a great tip: Rebecca recommends applying dry shampoo before bedtime to wake up with voluminous bedhead. "My theory is that either tossing and turning in the night rubs in the powder, or a full night's sleep allows the powder to completely soak in," she says. "Either way, it works." Genius! I tried it last night. You wake up feeling like Anna Karina.
