Why did men stop wearing hats?

I heard hats died out after World War II, because it reminded men of when they fought in the war (Soldiers had to wear hats).

What other reasons caused hats to die out?

I should’ve added “MOST men” to the question. Of course some guys still wear hats, but for the most part men don’t wear hats everyday.
