If you want bouncy curls and you have naturally curly hair...

The tool for you: Blow-dryer with diffuser, and styling product.

Why: The diffuser will help to prevent your hair from getting frizzy as you dry, Gibson says.

How to get the look: After towel-drying your hair, separate it into 1-to-2-inch sections. Using the blow-dryer with diffuser, dry your hair by moving from the top to the bottom of each section while working your way around your head. Then, Gibson recommends using a styling product for curls that isn't too heavy, such as a foamy mousse, to make each curl look more defined and to add shine (which is beneficial, since curls don't reflect light the same way straight hair does).
