Got a hot date coming up? While the sultry nights of summer inspire the steamiest of romances, they also can wreak havoc on a girl's hair. Heat and humidity, and the sweat that comes with them, can turn a smokin' style into a hot mess. Take some inspiration from these celebrities for hot date hairstyles that can not only take the heat but thrive in it.

Copy Julia Roberts and let your long locks fall into graceful, carefree waves. The look is pretty and girly while remaining utterly touchable and inviting.

Nothing feels better than getting your hair up off your neck when it's hot. To stay cool without cooling off your date, try Nicole Richie's boho braided updo. A loose, messy, braided updo conveys a free-spirited attitude that can inject some serious steam into a hot date.

Jennifer Lopez is a bon-a-fide expert on what is sexy and classy at the same time. A deep side part allows the hair to fall mysteriously over one eye, a look that is undeniably alluring.

When you go for the half-updo with volume at the crown, you echo the sexiest icons who reside in the subconscious of your date: Sophia Loren, Bridgette Bardot, Raquel Welch, etc., etc. Take a cue from America Ferrera and keep the look simple and tousled. You don't want to look like you tried too hard (Bardot never tried too hard).
