So I have a small dilemma.  In the shower, do you use shampoo on a bald head or soap? 

If I hadn't shaved my head 4 weeks ago, now is about when my hair would have all been falling out.  Definitely not something I wanted to experience.  I can't believe how sensitive to temperature change a bald head is.  Mine seems to go from super hot to annoyingly cool in an instance.
