cowlicks

it really depends on the severity of your cowlick and your hair type.
I know your a girl and im a bloke but i guess there are somethings that relate.
I have a cowlick that pushes my hair straight back but ive found that having your hair over an inch and a half on the fringe weighs it down.
my stylist used to leave my hair on the cowlick side a little longer than the other so it looked okay.
Nowadays I actually like the movement it creates and i just mess it all up and leave it.
It is possible to partially train your hair to fall a certain way and if you want to part it you should use clips and stuff and it should come right. If you want a fringe/ bangs i would opt for very thick ones with a lot of weight, and if you would like them short i wouldnt do it straight away - try some longer bangs before you go that way, that way you can see how its going to look.
a friend of mine at university has the same problem and we were discussing it one day and she actually has an undercut fringe with the cowlick and front being cut a lot shorter than the rest of the fringe, but not so short (ie - not removed completly) that she cant wear it up as well.
good luck
