Curly girls can get a twofer!
If your hair is curly like Leona Lewis', you probably (hopefully) already know that you can apply the right products while your hair is damp, and then separate and scrunch to get fabulous curls. If you love straightening your hair, but hate the time it takes to blow dry it straight, then go back over it with a flat iron, try this: Wear it curly one day, and don't get it wet when you take a shower that night or the next day. The following morning, flat iron your hair straight from its curly state -- it'll go much faster and save some damage on your hair.
