I have long hair down to my butt. I wear my hair long mainly because I have a serious thing for guys with long hair, and I figure it wouldn't be fair to demand that guys grow their hair long if I'm not willing to do so myself. I do get compliments on my hair sometimes; mostly from women, which I don't really care about, but it's nice in a platonic way.
I used to have a Mohawk for several years but when I got a new job a couple years back they didn't like it. Besides my hair is thinning now so I can't really do a good looking Mohawk anymore even if I wanted to have one. Now it's medium up top (about 5 or six inches) an short on the sides and back. Styled by slicking it back or combing it over to one side.
I keep mine quite long, down to the small of my back at present. How I keep it depends on how it behaves (It's typically long and a bit wavy, curling nicely at the tips), but most of the time it is either let down or tied up in a ponytail. A fair amount of the time it is braided instead. I've never been sure what to make of my hair; It is a chestnut color in most places, but in some places it's copper.
The shortest my hair's ever been was an inch long, and that was the day I was born :T
Right now, it's past my waist, but not by too far. I usually get it lopped to my shoulders from my waist every two years, but I'm gonna grow it long this time.
Its usually short, not in any particular style. When i was in school i had the piss constantly took out of me when i tried to have it like everyone else, and had the piss constantly taken out of me for when i didnt. Only reason i dont do much with it now is because the latter takes least effort.
When i was young my hair was nearly white, but then it just went to as dull a brown as you can get.
I like to keep mine at a somewhat medium length. The sides are long and the bangs are cut at an angle so I can sweep them to the side easier. Something like this: http://www.furaffinity.net/view/8396038/
I had short hair all throughout my childhood so I can never go back to those dark, boring days. :C
