THE LOOK A slightly wedged chin-length bob WHY IT WORKS "She wanted a change, and that was the purpose and the reason," said her hairstylist, Robert Vetica, author of Good to Great Hair. "Salma's had this style before and it just suits her so wellit's a great length, it frames her face, and it's not too short or too long." WHO SHOULD GET IT “This is a great cut if you like the versatility of wearing your hair wavy or straight. But if you're someone who always likes to pull your hair back, this won't work. It's just not long enough," Vetica said.
