Tattoos or scarification comes to mind. Weird piercings. Or funny hats.

I made up my mind very early that if/when I get bald, I’ll just shave my head. Makes no sense to me to hold on to half dozen hairs on my head. But I wouldn’t like to see everyone bald. I like seeing how people use their hair to express themselves. When I see someone with their hair dyed a wild color my only concern is how bad it may be for the hair and if I’m crossing that narrow line between looking and staring. But the look? Really not my concern. Makes the world a more interesting place to exist.
