Tip 1:

Start by applying a mousse like Nexxus GORGEOUS CURLS OR MOUSSE PLUS FOAM STYLER in order to help the hair hold up to moisture and humidity.  Be sure to distribute the mousse evenly throughout the hair, from the roots to the ends.

Tips 2:

Choose the right size curling iron for your hair.  Use jumbo curling irons to create bends and flips on shorter styles and to create face-framing waves on longer hair.  Use a  medium or large barreled iron to create defined waves all over.

Tip 3:

Use the proper curling technique to enhance each individual curl.  Hold the iron vertically and spiral each section of hair around the barrel.  Hold the curl for several seconds and then release.  If you want softer waves, extend each curled section with your hand.
