Nip/Tuck character Kimber Henry's curly hair?

How do I create big curls like Kelly Carlson's? Are these permanent curls or just temporary setting? See photos below:

Nip/Tuck character Kimber Henry's curly hair?

It doesn't look like a perm to me. Just use large rollers and let hair dry naturally. May want to put something like dippety doo on top of the hair after rolling to hold the curl.
