This was in my schools (LSU) daily newspaper today....Thought you might enjoy. It may be small, but it does show that LSU is turning more into a longhair friendly environment. I am no longer the only guy on campus with waist length hair and there are a large number of guys with hair to their shoulders.

The longest ive gone without using shampoo (I used conditioner only) was about 2.5 weeks. It was disguisting. But I think I might actually go see the guy that was interviewed for the paper and ask him how the talc powder was used and give that a try.
