One truly excellent way to emphasize and even exaggerate the shape of your face is to wear your hair in an updo that is pulled tight to your head. Be sure to employ a deep side part and plaster any bangs that you have to your forehead. Ricci is a true exotic beauty, and it still shows in this picture. But her drill sergeant hairstyle ages her about 20 years.

It's true that the oblong face can be very challenging when it comes to hairstyling. But sometimes, the simplest solution is also the best. A longer face can pull off a super-clean tight-to the head updo like Rowland's for all the reasons that a round or square face can't. The tight lid emphasizes the width of a woman's face. Note that there is absolutely no height or volume at the crown. That's key to the success of this hairstyle. This is an extremely chic look that most other women can't wear. Go for it!

This updo fails on Parker for the same reasons that would have worked on a woman with a rounder face. Height at the crown creates even more length on an already long face. The little fringy bangs serve to make the face look even skinnier and actually create the illusion that her head is too tall for her hair.

Nothing looks better than effortless chic. Biel's updo will work for everyone. The soft fuss-free bangs (you can center or side part) and easy pieces framing the sides of the face create a confident approachable glamour. The back can be quickly wrapped into a french twist. If you have a round or square face, back-comb first, especially at the crown, to create volume at the top.

Here's a bonus look for the glamour girls in the crowd. The reason everyone looked so fabulous in the sixties is because they all wore this perfect updo. But seriously, get yourself a long, thick hairpiece and braid it. When you need to look insanely glamorous at a moment's notice, pull your hair into a ponytail at the top, tease the living sin out of it, turn the ends under and secure with bobby pins. Then wrap the whole thing with your braided hairpiece and secure with more bobby pins. This look is incredibly flattering on nearly everyone. Just experiment with the placement of the updo and with releasing pieces around the face if you need it.
