Round -  Round hairline and chin line, wide face and round cheeks
If you have a round face shape, the goal here is to slim the face. Hair below the chin line should be worn with a face-lengthening center parting. For hair above the chin line, wear an off-center parting to break up the roundness. 

Square - straight hairline, angular jaw with wide face
Your hairstyle should try to soften the sharp angle of your jaw line and minimize a squared-off forhead look. Hairstyles that emphasize the cheekbones are most flattering, so short layers (cut into longer hair) that swing foreward onto cheekbones will look great. 

Triangular or Pear - wide chin and narrow forehead
When choosing a style for this face shape, you should seek on a look that narrows the chin and widens the forehead to balance proportions. Wear your hair wide and full at the top  and temples, brushed away from the face and up toward the ears to widen forehead. 

Heart -  narrow jaw line, wider at eyes
If this is your face shape, you'll want a hairstyle that extenuates the jaw line and narrows at the eyes. Heart shape faces need a softer, curlier style. a chin length look is perfect. The objective is to create width around a narrower chin. Side slanted waves draw attention away from the jaw line. Best looks are full curly / wavy bouncy. Your hair type will also determine the best style. 

Oblong - Long and slender, about the same width at forehead and just below cheekbones. May have a very narrow chin or a very high forehead.
Hairstyles for this face shape should add width and fullness to the sides of the face and around the eyes, cheekbones and ears. This shape benefits from a low side parting, with a sweep of hair brushed across the forehead and secured with a  butterfly clip.
