I've got a question for your guys who shave it all off, especially those of you who work in the south. Do you have a problem with sweat from your head running down into your eyes? I keep my hair pretty short and it seems to wick the sweat away from my scalp where it then evaporates. My hair actually gets a little 'crusty' from the salt by the end of the day. I think the evaporation helps to cool my head. My forehead, on the other hand, has to be wiped dry at almost every stop to keep the sweat out of my eyes. I figure with a bald head, there's just that much more surface area that's sweating, so therefore, more runoff.
