If you ask us, every woman should own a flat iron. Why? Well, first of all, the possibilities聽are endless聽(you can even curl your hair with it!).聽Secondly, there鈥檚 nothing we love more than a classic, sleek hairdo 鈥 perfect for a high-power meeting in the office or a sexy night out on the town. These celebs show us how any length or texture of hair can get some serious star power with the help of a straightener.
