Spicer explains her decision to go without make-up in a comment piece for the Daily Life, writing it was sparked by a question from her daughter asking why women wear make-up and men do not. That question inspired a January 2014 TED talk titled 'the lady stripped bare' in which Spicer removed her make-up, dress, high heels and sprayed her perfectly-coiffed blonde hair with water. The talk went viral and Spicer has been gradually weaning herself off her extensive grooming regime ever since.
Throughout this year she has given up spray tans, blow dries, make up, moisturiser, plucking out her chin hairs and shaving her armpits - saving her $700 dollars (£391) per month. Next up, she will stop dying her hair and shaving her legs.
"Grooming is a cost of doing business borne by women, not men," Spicer writes.
"I couldn't be happier, because I've bought myself an extra hour a day: more time to play with the kids, ride the paddle board and strum the guitar. Oh, and work. I'm definitely more productive. The best thing? I feel like the real me, instead of a painted doll."
"I’m judged on my interviews, my appalling sense of humour – on how I do my job, basically. Whereas women are quite often judged on what they’re wearing or how their hair is," Stefanovic said of the experiment.
