I wear a ventilated Hat when out doing tractor work or gardening, and maybe on occasions I'll wear a smokers hat when going out somewhere fancy, But not much on everyday wearing them, simply because I think they make you prematurely loose hair, Back in the '90s I worked a young man was in his mid 20's, He always wore a cap, he had long hair hanging out from all around it ,one day on the way to work he was setting in the rear seat of truck , I happen to get a glimpse of him through the rear view with his hat off while scratching his head, I was amazed on How Bald his head was on top when having so much hair hanging out,

Needless to say he carried a nickname of Baldy from that day on

....... How many of you can relate to this?

and is it due to wearing a hat/cap?
