Kate Beckinsale has got a faux bob which is the best way to style the hair when you are planning for a prom. To get her hairstyle first spritz the hair with a beach spray before you begin the styling. Next blow dry the hair using a diffuser to get a good and beachy texture. Then create a center part and collect the hair loosely near the neck to tie it back using elastic. You must keep the sides loose to create a faux bob. At last take few little amount of hair gel on your fingers and wrap a few strands in front to get more defined waves.
