Let me very firmly indeed declare myself on the side of the author, here:
I look dreadful with both white hair and blonde hair. I am a dark-haired woman. And so shall remain.
And there's the rub. Women will admire Anna Ford and the rest of the glamorous grey brigade, but they will hesitate to follow suit. We don't want to go grey because of ageist prejudice, but the guilty secret is that many of us are scared we haven't got the cheekbones or the chutzpah to carry it off. My suspicion - and OK, it's deeply unsisterly - is that some women are happy to turn silver because they know they still look hot; it's not so much authentic ageing as a subtle assertion of superiority.
The other problem about grey hair is that it is such a high-maintenance option. You don't have to get your roots retouched every five minutes, but if you want to stay fabulous, the rest of your grooming has to rise exponentially. Flawlessly styled hair, immaculate clothes and perfect make-up are indispensable, as is a trim figure.
