Star Hair: Get the Look!  What Not to Wear's hair guru Nick
Arrojo tells you how to style your tresses like Jessica, Sienna
and eight other celebs. By Serena Kappes   How to get the look:
1. Use a volumizing product to blow-dry and tousle hair with
fingers. 2. In the jar, blow-dry a small amount of pomade until
it liquefies. Dab onto palm and apply "to create separation and
texture," says Arrojo. 3. For a "more carefree look," use a
curling iron to loosely loop the ends.  Bonus tip: "Add
extensions to give your hair pieces of length in areas," he
says.
