This soft graceful updo looks good on just about everyone, but it's especially well-suited for those with a square face. Updo hairstyles threaten to accentuate an angular jawline and can be unflattering. This style, with its soft sweeping lines and face-framing tendrils break up the angles of the face and obscure a sharp jaw. The feminine curl near the face draws the focus upward to Alba's eyes. Dreamy!

Square-faced women frequently have very strong jaw lines and prominent chins. With the hair pulled completely off the face like Aniston's is in this updo, the eye is immediately drawn to the most prominent feature: her chin. So, unless you want people looking at your chin all evening, this is a bad thing. Always use long pieces of hair around the face to soften the jaw and draw focus to your eyes.

If you have a heart-shaped face, your primary objective is to keep your forehead in check and not let it become the only thing people see. Panettiere's romantic updo is a great example of how to do this. A slightly off-center part de-emphasizes the face's heart silhouette, and the wavy side-swept bangs place attention on her eyes. The heart shape face is very appealing, so you don't have to go crazy trying to correct it. Just watch that forehead.

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!
