"I would recommend the Wella Oil Huile," says Benvenuto. "Putting a light layer on your hair will protect it from the sun and chlorine if you decide to take a dip!"
Another option is to wrap your hair up in a silk head scarf to protect it from water. A hat will do the same thing, but it could leave a dent. We also like plaiting our hair into loose milkmaid braids, which will just add more beachy, wavy texture when you take them out. And if all else fails, scoop your hair off of your neck and twist it into a loose bun.
