Men's haircuts reflect the uncertainty in our times
"Men are going in for old-fashioned styles at the moment, harking back to the Mad-Men era and even earlier than that, to the 40s. What we find is that in times of uncertainty, you go with what you know."
It's a look that is certainly popular at the moment. Even David Beckham, the man who has spawned more hair trends than almost any other, is now sporting a Don Draper-like style.
But it's not only the average man on the street that senses that straightened times call for a short back and sides. When Mrs Thatcher was in the mood for swingeing cuts, her new man at the Treasury, Nigel Lawson, said goodbye to his own raffish, collar-length tresses.
"It was immediately after the 1983 general election and Mrs Thatcher asked me to see her," he says. "She offered me the job of chancellor of the exchequer, which I was very, very pleased to accept.
"She only gave me one piece of briefing for the job. She came absolutely straight to the point. She said 'Nigel you must get your hair cut'. She had the idea - and she may have been right, I don't know - that somehow the financial markets wouldn't take altogether seriously a chancellor of the exchequer who had long hair."
It's not just classic cuts that men are going back to the traditional barbershop is enjoying an invigorating revival, say some. After the fashion for unisex salons in the 60s and 70s, and the recent rise of "metrosexual" man, it's suggested by some that men feel more comfortable in this unambiguously male environment.
As a barber, after so many years, the customer becomes a close friend they tell you everything. Being a hairdresser is like being a priest really.
At Geo F Trumper in London's Mayfair, barbershop to the great and good. Staff there say great affairs of state - as well as other affairs - have been settled over a short back and sides.
As David Cameron likes to say, we're all in this together, and what could be a better leveller than the handiwork of a good barber?
