My hair is getting a lot longer... I'm thinking of letting it go shoulder length and see how managable it is. If it's annoying, I'll just have it cut back to where it is now, borderline at my neck.
The only real annoyance it creates at the moment is being blown around by the slightest wind current... That and it takes a lot longer to clean in the shower.
It makes me wonder as to how women can deal with long hair.
