I've had a short pixie cut for many years now. Last summer I did attempt to grow it out and got it to my shoulders... but it was so damn hot that I cut it all off. Having a pixie is a blessing and a curse... while it's really easy to care for (I can dye it like crazy and my hair doesn't get damaged because it's very healthy and I can wash it and not have to wait for hours for it to dry), I also have to trim it up very regularly so it doesn't get all straggly looking.
Sometimes I do wish I had long hair - past my shoulders - because I wouldn't need to cut it so often. Plus, not to brag, but I have very nice hair. Soft, shiny, lots of body and naturally wavy. When my hair was longer, all I did was wash/conditioner then comb it and allow to dry. What my hair looked like naturally (with no styling) is what many women spend lots of time and money to get their's to look like. So yeah, what do I do with that lovely hair? I chop it all off. *shrugs*
