Carrie Bickmore was tempted to go back to blonde, but she would have broken the law.

Almost seven months after becoming a brunette, The Project‘s Carrie Bickmore has shared that her hair colour has been a hot topic for the bookies, with betting agencies creating odds about when she would return to blonde.

Because ICYMI, the hair of our national television presenters is a very big deal, people. A very big deal indeed.

Sharing the bizarre story with fellow panelists Peter Helliar, Waleed Aly and Rachel Corbett, Bickmore said, “Before Christmas, there were [odds on] when would I dye my hair back blonde.”

The 36-year-old continued, “If I did it before Christmas the odds were so good I thought if I could do it before Christmas I could pocket some sweet cash.”

The mother-of-two then added laughing, "It's highly illegal, so I couldn't, but you know, it was an option."

After a lifetime of being a blonde, Bickmore changed her hair to a dark brown in August as part of her partnership with Garnier.

“I’ve had the same colour hair for 35 years and I was bored and I thought, ‘Why not?'” Bickmore said following the big reveal. “I’m giving it a whirl!”

“I’m giving it a whirl!”

The change wasn't without controversy and comedy, however, even Bickmore's own grandmother didn't recognise her.

“Nan doesn’t like my hair,” Bickmore told her co-hosts in October.

“Nan watched the TV for two weeks and thought I’d gone on holiday, and they’d found a girl with … different coloured hair that sounded like me to fill in for me.”

Now, less than a year after the change, Bickmore seems to be returning to her blonde roots, with her hair looking noticeably lighter. Blonde, brunette, red, black or blue, though, we'd love Bickmore and her hair any old shade.
