Visions of “surfer girl” hair conjure up shiny, healthy, photogenically tousled locks. But as anyone who’s spent the day in the sea well knows, the ocean can be brutally drying on your strands. To the rescue comes Kerastase’s Soleil Aqua-Seal ($36), a waterproofing veil that protects hair from UV rays and dehydrating salt water. The best part is its transformative formula: the pump bottle dispenses the seal in cream form so there is less mess, but it quickly turns to oil in your palms for easier application and detangling—so we can finally surf easy with no fear of sea-hag hair.
