Firstly, I'm a guy. Just useful to state that when we're talking about hair. What looks good on a girl probably doesn't on a guy, and vice-versa.
I have very dark hair, just short of black. Wish it would have just been black to be honest. Tempted to dye it though I constantly have people telling me it's practically black anyway. Don't want it too look gothy either. It's straight as hair comes. Not so much as the gentlest of waves. Length wise, it fluctuates. When I get it cut, I get it cut so it's just coming over my ears. By the time I go for my next haircut, I generally let it grow to the lenght where my ears are just covered and my fringe length wise is reaching my eyes. Sometimes gel it. Depends how I feel.
