I'm seriously considering getting my hair cut off. Same reason as Emma too. I'm in a new stage of my life and I want to do something different and I want a bit of a change.
I have straight, thick, brown hair. And though it's soft and fluffy and people like running their fingers through it, it's really high maintenance and sometimes I just don't have the patience for it. I've talked to my friends about getting it cut for quite a long time and they either say "YEAH! Do it!" or "No don't! You're hair is too majestic!"
I have my high school commencement ceremony in November, and I promised my friends that I would keep my fluffy locks for that and do loose curls with it, because that's the way they like it. After that, I'll look into what I can do. I don't know if I can pull it off, but we'll see what my hairdresser says. My biggest fear is looking like a guy!
My hair grows fairly quickly, so if I like my older look, it's not like I'll have to wait a long time for it to come back.
