A hair cut is not a trifling matter. This, men do not understand. To a man, a haircut is a way to kill fifteen minutes of a lunch hour. It involves no more mental taxation than reclining in a swivel chair arguing with a barber about Shane Warne’s discipline problem.

For women, a haircut is the fastest route to an identity crisis. Period. It can coincide with that too. I should know – I just had one – a haircut, and a freak-out. Some people will no longer recognize me because I’ve gone short – I had a whole 3 centimetres cut off. For me, a change is nowhere near as good as a holiday.

Men should also know that women have a fraught relationship with their hair because hair the only thing that can be changed at whim. And let’s face it, most women grow up wanting to change everything about themselves. Well at least I did.
