But at the 2019 ARIA Awards, Martha decided to debut the first of her dramatic dos.
Walking the red carpet with her boyfriend Michael Brunelli, the MAFS bride looked radiant in her orange and pink dress but fans went wild for her new bob cut.
"In love with your new cut," one wrote on Martha's Instagram page.
"HOT! I loveeeee your hair!" another penned.
"Hair is gorgeous!" exclaimed a third.
When lockdown rolled around, Martha joined the many Aussies who used their time at home to undergo a big hair change.
In an exclusive chat with New Idea last year, the reality star and influencer said that her lighter colour all started out of boredom - at least it did for boyfriend Michael who bleached his hair blonde.
"He just dyed his hair and then my sister was up here with us and she is peroxide blonde and I was like 'I can‘t be the only one that’s not in the club, I need to do something for my hair too,’ and that triggered me to start colouring my hair," she confessed.
That light brown look certainly is one of our faves.
It didn't take long for Martha to switch up her light brown/auburn colour to match her boyfriend's blonde look.
After all, they say blondes have more fun and her fans certainly agreed.
"This hair is absolutely gorgeous," one wrote on Instagram.
"You look so great as a blonde," complimented another.
"So hot," stated another.
Of course Martha couldn't start the new year without a jaw-dropping new look.
Posting a video to her Instagram account in January, the MAFS beauty shared a video of herself showing off her change from blonde bob to long mermaid strawberry blonde locks.
"Time to change my hair up, I have so much fun changing my hair," her voiceover said in the clip.
Martha credited ethically-sourced hair extension company LDL International for her look and revealed that she reckons they make "the best hair extensions in the world.
"Safe to say I am so happy, so obsessed."
