Scrape it back: A low ponytail (in an elastic or a simple barrette) is the all-time chic classic. Polish off the ends with styling cream or shine serum. At the pool or ocean, run deep conditioner all the way through your hair and leave it on for the day.
Saltwater sexy: There's a reason hair looks so good after a dip in the sea: Salt is a natural texturizer. To do it without the ocean, these sprays mix salt with super-conditioners—not to mention pretty scents—for the same effect.
Messy braids: The sexiness of this is its Swedish-starlet undoneness. Spray on leave-in conditioner (for a very loose hold). Weave in a ribbon for a touch of drama.
