1.  On freshly washed hair, towel dry your hair but DON’T brush it out.  If your hair has no natural curl, brushing it will only make it more straight.  Instead just shake it out or run your fingers through it.
2.  Apply curl mousse to the ends, scrunching it up as you apply.  

3.  Blow dry your hair with a diffuser attachment on the end.

5.  Using a 1/2 inch -1 inch curling iron, wrap your hair around the outside of the barrel instead of clamping it in.  This will create a looser wave.
