I have incredibly curly hair, and after years of trying to figure out what to do with it longer, I decided to just buzz it all off. Now that it's significantly thinned, due to T and my oh-so-wonderful genetics, I can't let it get much over an inch long before it looks atrocious.
So, even though it's a little boring short, at least the upkeep is cheap--- I bought a Conair hair trimmer at Wal-Mart for 20 bucks and haven't paid for a haircut in 2 years.
