I have been told I have "Resting Bastard Face" so I don't normally look jolly. Shaving my head did cause some people to be extra intimidated when I am angry at them. This I find sort of ironic because I don't see myself as a mean person, I don't use foul language and I am not a violent or "Tough guy" I'm pretty laid back and am what I like to thank of as a gentleman.
However, once I shave my head I got told a lot that i look 'Scary" which I don't myself see.
Having a full bald head has not been commonplace for a long time, and it's slowly becoming more recognized. I think it will take people a while to see a shaved head differenty.
