Grey hair and wrinkles are finally becoming something to celebrate.

Is there a new acceptance, and even celebration, of female aging, or has the mega-billion dollar beauty industry just latched onto a new way of parting women from their money?

It's being called a revolution, the "new black", a new age of aging, where more and more older women are becoming comfortable in their own sagging skin.

The message is spreading that grey hair and wrinkles should be celebrated, despite the youth-obsessed fashion and beauty industry.

Even ex-Baywatch star Pamela Anderson is on board at the age of 56, appearing at Fashion Week makeup-free. And just last week Vogue featured 88-year-old actor Maggie Smith at the centre of fashion label Loewe's new campaign.

Bagust says she doesn't know what opportunities she's missed since she quit as a blonde, but the change has opened up new opportunities, including the podcast series which has a mission to "carve out a sanctuary for women in this age bracket, to help them realise they are not alone".
