2. Sleek, Straight Hair

Sleek, straight hair is sexy because it looks so healthy. It has shine, which is something that can be lost in other hairstyles by the time you add in teasing and tons of hair spray. A flat iron can help you to achieve the sleek look you're dreaming of. Even if you have naturally straight hair you'll probably still want to use a flat iron. If you need a bit more shine, rub a few drops of hair oil onto your hair before you blow it dry. It may take a few tries before you get this exactly right for your unique hair.
