Right now its really short (maybe 1/8th inch on top, 1/16th on the sides). I grow it out to 1-2 inches when I can, but when the sheds hit, I cut it down. I had a big shed last month, so in two more months when that hair starts growing back, hopefully thicker then before <crosses fingers>, I'll have enough to grow it out again with confidence.
Although, I must admit, I'm starting to like having it this short. minoxidil apps are easy and theres no hairstyle to mess up, AND I've actually been seeing more women checking me out, to my suprise. (then again, I have been hitting the gym too).
