Jessica Simpson is the ultimate blonde bombshell, and it's no coincidence her stylist Ken Paves is always by her side. OK, they are best friends: But still, Jessica's soft, layered waves are the work of a genius.

Jessica tends toward looks that are romantic and sexy, so she often wears her hair down in loose waves. But she also goes for updos on the red carpet, which are either loose or very structured -- either way, she prefers to look very "done." So if you're using Simpson as inspiration this coming prom season, don't shy away from the hairspray.
