Step 1: Start with a volumizing mousse and blow-dry. Or, if your hair is already dry, dust on some volumizing powder or dry shampoo to give roots a little boost.

Step 2: Wrap small sections of hair around a curling iron, but make sure to curl only the middle of the sections—keep the curling iron away from the roots or the ends. (This is where the easy, laid-back factor comes in: curls that span root-to-tip end up looking less natural and more over-styled).
Step 3: Brush out curls and finish with hairspray.
