Used to be Sly and a member, several years ago. Let it grow back for no particular reason. Don't have MPB, though getting a bald spot on the back of my head, just like my father had. I am on the fence and when I last shaved my head, my life was in a rut. Now in a deeper rut and I won't use my post to air personal problems or issues. I'm on a couple of psych and men's health sites for that.
Shaving my head won't magically transform my life, but radical changes, whether physical, emotional or situational, can be the catalyst to get one off of autopilot.
