Hairstyling Tip of the Day: Use a round brush made of the same material as your favorite blowdryer/flat iron. For example, if you love the results you get from using a tourmaline flat iron, try using a tourmaline round brush, such as this one by Spornette, while blowdrying your hair! Doing this will give you the same style in half the time! There is a round brush for almost any type of styling — tourmaline, ionic, ceramic, anything!
