Outside of my old man and grandfather, I don't recall anyone my age that shaved bald when I first started.
Back in high school, there may have been 2-3 other dudes with thinning hair like me, but I was the most progressed. Lucky me. LOL
In college there were other a handful of shaved students but the school was big and I didn't know them (they were prob grad students.) Still, it was good knowing there were other baldies on campus, so I didn't feel too eccentric.
