We all love the charming and kooky Kelly Killoren Bensimon, one of Bravo TV's Big Apple Housewives. Even if you're not her biggest fan, you can't deny that Kelly's got pretty fantastic hair. In the adorable clip below, Kelly tries a "hair cocktail" created by her hair stylist, Kathleen Flynn-Hui of NYC-based Salon A.K.S. Made from four ingredients (olive oil, sea salt, lemon juice, and vodka), this DIY concoction claims to treat lackluster locks. "Olive oil adds shine, sea salt removes residue, and the lemon juice and vodka bring out natural highlights," says Kelly in her bathroom. And the verdict? "It worked!" We're a little skeptical, but if this calorie-free cocktail works for New York's finest, then we're on board.
