As Deborah Knight moves from strength to strength when it comes to her career, she likely fields unsolicited commentary on her wardrobe and makeup choices.

After moving on from Today, Knight has started a new radio gig and her on-the-job styling has changed from hour-long sessions with a range of stylists to a more low-key look.

However, it is something that her followers on social media can’t help but point out.

"To those who comment that I 'look so different' when I post pics without the full TV hair and makeup - no s--- Sherlock!" the 2GB Afternoons show host tweeted.

"An hour with a professional hair and makeup artist is time well spent for good reason. Always feels like such a backhanded insult.. Au naturel is OK too tho."

Knight has previously spoken about her preference for a more natural look, explaining to 9Honey that the first thing she does after coming off-camera is wiping off her makeup.

"Because while a suit of TV armour is essential, nothing beats going au naturel," she wrote.

"I've never been a fan of personal grooming that requires excessive time and attention. I don't enjoy the fussing at a hair salon, the smell of fake tan makes me feel ill, and I never find massages all that relaxing."

Knight explained that in her “normal life”, she allots no time at all for hair and makeup.

"I smother myself in moisturiser, but I don't wear makeup as I don't like the feeling of foundation or powder on my skin," she wrote.

"And on the rare occasion that I do apply mascara or eyeliner, it always inexplicably ends up smudged or smeared nowhere near where it was meant to go."

As for styling her hair?

“Running a brush through my wet mop after a shower is pretty much my styling regime."
