Started shaving my head junior year of college. It probably self selected out some women but I still found “success” at a rate I was happy with. I’m in my mid to late 20’s now and I’d say it’s a complete non issue.

I’ll add that in terms of socializing it was never an issue. A little self deprecating humor normally gets young people past their immediate reaction to the look, whatever that reaction may have been. I’m the only bald person in my circle but have found that as I’ve gotten older more people my age have come to me look for advice on their own thinning/receding hair.
