Firstly I think this theory is complete nonsense. Before the 20th century women tended to always have quite long hair, even if it spent most of its time tied up or under a hat or bonnet or whatever. But in the roaring 20's, during the Flapper/Charleston era, the 'bright young things' cut their hair in bobs. This was a time of great affluence among the upper class, ended by the Great Depreassion in the 30's, by which time women tended to have longer hair!
The next time women went for short hair was in the early years of the 'swinging sixties', with the Mary Quant bob - again a time of affluence - but then came the hippie era long hair which was during slightly harder economic times. Short hair came back in the early 80's as a result of Punk and of yuppism.
I like long haired women so it would be a pity to see it go out of fashion.
Maybe we could try to find a correlation between facial hair on men and the economy!
