Doc, once you're past the "itchy" stage a beard is not much different in the heat than a shaved face...The itchy period combined with heat is real tough, but after that, it's easy.
I went big bearded for years. One day I got sick of it (after 15 years) and even though I hate shaving, I busted the beard off. The very first thing I noticed was that people were more willing to talk to me! My jokes were funnier!?, I was shocked. Could this really be true? I swear it is. Big beard = scary freak, no beard = not so bad. I'm the SAME DUDE!!! Anyway, After establishing my shaving ritual I discovered that Schick 3 blade disposables and Barbasol shave creme are "it" for me. Gillette razors and fancy shave sauce were killing me.
