You might think you can just throw your hair back and let it fall where it may. But have you considered how your hairstyle can change the way your face looks? If you want to look your best, then you have to analyze your face and find the style that will flatter it.
In theory, a center part makes your face look wider. So it should work best on people with a long and narrow face, right?
Liv Tyler certainly looks great with one here:
However, I think her appearance owes more to the volume and shine of her hair. A center part combined with flatter, darker hair is not nearly as good.
She also looks ok with a center part and bangs. You can see a section of hair that ends around her mouth level. This is a great length for layers that will add width around the middle of the face.
A side part with volume looks terrific. The widening effect is enhanced by the big round earring, the short hair length, and the fact that one ear is showing. The way the front of her hair is rolled off her face and cascading down the side adds interest, because it makes her face seem like it curves in around her eyes instead of being shaped like a rectangle.
Looking at the last photo, you may think that Liv Tyler looks best when the part of her hair is aligned with the arch of her eyebrow. But you’d be wrong, because basically anything’s better than this monstrosity:
So clearly it’s not just about where she parts her hair. The most important thing for a long, narrow face is having volume to add width around the face. Width can also be achieved by tucking your hair behind your ears and wearing large earrings (studs are better than long drop earrings, which could make your face look longer).
