Hairstyle is a reflection of your personality.A trendy new hairstyle can change your appearance completely. It's very important to choose a hairstyle that best compliments to your face. To choose the appropriate hairstyle you should first think of your face shape.

The basic types of face shapes are 1) Oval 2) Round 3) Oblong 4) Heart 5) Square & 6) Diamond

Here's a guide to What's Good and What's Not in terms of Hairstyles for your face shape:

Good: Chin-skimming bobs, blunt bangs, long, beachy waves (think California surfer girl).

Not Good: Short layers that add height on top of your head. This will make your face appear long. If your hair is thick or curly, avoid a blunt cut. You'll look like a pyramid.

Good: Soft, graduated layers are a great bet because they make your face appear slimmer and tend to remove bulk and weight from the sides. Short hair styles with a swept-back direction or hair styles that are longer than chin length. By layering the top to achieve fullness and keeping the rest of the cut relatively close to the face, your face shape will appear longer and narrower. Bangs are flattering, but keep them long or sideswept.

Not Good: One-length, blunt cuts if you have short hair. Curly, short hair is also a no-no. These only emphasize your roundness. A rounded haircut ending at the chin will certainly add weight to your face shape. Because the widest part of your face is at the cheeks and ears, you need to avoid having the fullness of the cut here as it will make your face appear wider.

Good: Side-swept bangs. Chin-length bobs are also ideal for us because they create the illusion of width. We look great curly or wavy (these also add width). Short to medium lengths. Fullness at the sides of your face. Soft wispy bangs. You'll want to balance the look of a long and slender face. Soft wispy bangs will shorten the appearance of the length. Fullness at the sides of your face will add width to the look of your face shape. Layers work great with your face shape, as they will add softness to the straight lines in your face. Try side parts, and you may be able to wear straight back styles.

Not Good: To much hair length . . . your face will look even longer! Too much height lengthens your face. Center parts. When your hair gets past your shoulders there is a good chance it is doing you more harm than good.

Good: Chin-length or longer styles. Side-parted hair styles. Swept-forward layers around the upper face, gently wispy bangs. A chin length bob is great on your face shape! This creates a balanced look by giving fullness where you need it.

Not Good: Short, blunt-cut bangs and harsh, choppy layers. Short, full styles that emphasize upper face. Height at the crown. Severe, slicked back looks. If you are a dramatic heart shape, the short full styles with tapered necklines which emphasize the upper face will make you look top heavy. Too much height at the crown will give the appearance of a longer and narrower chin.

Good: Your face shape is balanced and dramatic. Try a variety of styles. Almost everything works with your face (as long as you are a true diamond). You can wear shorter styles, however if you are a dramatic diamond shape you need to leave weight in the back nape area like a heart shaped face. This will achieve more balance between your dramatic cheekbones and more delicate chin line.

Not Good: You can do just about everything, but try not too wear to much hair on your face, thereby hiding your great features.

Good: If you have a square face, you'll want to play down your strong, angular jaw. Texture, in the form of curls or choppy ends, do this brilliantly. Short-to-medium length hair, especially with wave or roundness around the face. Wispy bangs. Off-center parts, height at the crown. You want to soften the square look of your face with layers and wispy looks around the face. Height at the crown will elongate your symmetrical shape. If your hair is straight you may want to consider a body wave, as some curl or wave to the hair will achieve a nice balance to the straight features of your face shape.

Not Good: Long straight styles that accentuate square jawbone. "Linear" straight bangs or center parts. A straight bob ending at the jaw line is the wrong thing to do for your face shape. One-length bobs (especially chin-length) and blunt-cut bangs. These will make your face look even more square.
