The reason why Bipasha's hairdo got so many headlines was the precision of each layer in her bob. Says Sapna, "Precision-cut bobs are huge this year, especially when coupled with a fringe on your forehead."

But before you go all gung-ho for the chop, make sure it's shape will compliment the shape of your face. "Precision bobs should be carefully crafted to accentuate your unique facial structure - for example, if you have a long swan-like neck, your bob should highlight it than hide it," Sapna elaborates.

Wondering if a precision cut will suit your hair texture? "These bobs work best with straight or slightly wavy hair. The length varies from ear level to shoulder-skimming level - choose your length before the stylist uses her scissors on them," warns Sapna.
