Well, I am a girl, but maybe twice a year. I am really lazy about cutting my hair. I aim for every 12 weeks but then that somehow turns into 6 months. I don't color my hair or really do anything to it though, so it stays pretty healthy.
Every two weeks. I am a man in uniform. I go with a low fade, half from the bottom up and around the ears and sideburns then faded into the top of my head with some hair to groom on top.
Supercuts once a month. I find a stylist or two that I like and I stick with the same person. The same two stylist have been cutting my hair for close to two years.
Just got my first haircut in two years (finances have been tight), and I must say I feel better. Looked like someone got done shaving a black Saluki when all was said and done. I'm going to try to keep this better maintained, since I like the style and I think I can do it myself, maybe with a little help from SWMBO.
