Yeah I love that beginning by the way. Best military movie.
Like what has been said above, it was against regs (in the Army) to shave your head completely for a long time. They Sly look was considered a "fad" haircut. That has been relaxed over the recent year as shown by GEN Ray Odierno, commander of the US troops in Iraq. That all being said, after having been on both sides of basic training (in it and cadre running it), I think you might just want to consider letting your hair grow out a bit. I don't know about AF boot camp, but in the Army, the last thing you really want to do is to do anything that actively seeks out attention. Drill Sergeants have wonderful ways of giving it to you! The amount of time you have to care for your skin/hair is also going to likely be restricted. Again, I sure could be wrong. Given what it was like when I went through, I'd wait until you get to whatever the AF's equivalent of AIT is.
Sounds just about like what I would have expected. Part of the purpose of Basic is to break you down and make you just another "one of the soldiers."
