What Haircut Suits My Face Shape

Oval

The length will be equal to 1 ½ times the width.
Oval face shapes have well-proportioned and balanced features - a narrow forehead, wide cheekbones and a small chin - and suit any hairstyle, long or short, straight or curly.
Celebrities with oval face shapes are:
Charlize Theron, Tyra Banks, Angelina Jolie.

Oblong/Long

The width of the forehead is about the same as just below the cheekbones. The face is long and sometimes the forehead is very high.
Long faces suit most styles but they should all have volume to prevent the face from being dragged down. Full bangs can also work well.
Celebrities with rectangular face shape are:
Gwyneth Paltrow, Hilary Duff, Gisele Bundchen, Sarah Jessica Parker.

Round

The face has the widest point at the cheeks and ears. The face is clearly rounded around the chin and hairline.
If you have full cheeks, the wrong haircut can make your face look chubby.
Try cropped styles to give your face more definition or get bangs swept to the side. You could also go for feathered or layered hairstyles.
Celebrities with oval shaped faces are:
Kate Winslet, Hayden Panettiere, Marilyn Monroe.

Square

The shape in which the jaw line and the hairline are square.
A broad forehead and a strong jawline usually dominate, so go for long whispy layers or soft waves to slim down the wide areas and balance your face.
Celebrities with square shaped faces are:
Jennifer Aniston, Dita von Teese, Jessica Simpson.

Heart

Similar to oval, but this face shape's bone structure narrows and has a chin that's defined and pointed. Avoid bangs and balance small jaw lines with styles that are fuller at the ends to widen the chin and jawbone.
Celebrities with heart shaped faces are:
Katie Holmes, Mary-Kate Olsen, Rachel Bilson.

Triangular

The face that has a dominant jaw line that narrows towards the cheekbones and temples - reverse of the heart shape. You need hairstyles that balance out your prominent jaw.
Lots of layers will help to achieve fullness through the upper part of your face. Hairstyles with volume at the crown, off center parts, wedges and shags look great on you.
Celebrities with triangular shaped faces are: Celine Dion, Liz Hurley.

Diamond

The face that has equal width around the jaw line and forehead, and wide cheekbones. The diamond is a cross between the heart and the oval.
You can easily experiment with a variety of hairstyles - almost anything works for you. Bangs can work to shorten the faces and soften the pointed forehead. Tuck your hair behind the ears to show off your wonderful bone structure.
Celebrities with diamond shaped faces are:
Scarlett Johansson, Kate Bosworth, Rihanna, Madonna.
