Hot weather means a whole host of new hair problems, but we’re fighting limp and greasy locks the old-fashioned way – with dry shampoo. Except there’s nothing old fashioned about these follicle fixers. We love the Fekkai powder for its all-natural formula, as well as its narrow opening that prevents spillage. And the Batiste dry shampoo gives our hair unexpected volume and keeps our blowout in tip-top shape (long after the blow dryers have been turned off). High and dry? Yes, please.
