Shaving your head can be daunting, but not nearly so tough as battling leukaemia.
That's why Ellie Tucker braved the World's Greatest Shave on the weekend.
The 35-year-old - one of the latest group of medical interns at Wollongong Hospital - raised almost $5000 for the Leukaemia Foundation through her efforts.
And she's donated her hair to be made into wigs for those with hair loss due to cancer treatment.
"I think it is important to support anyone going through chemotherapy who doesn't have the choice about losing their hair," Ms Tucker said.
"I feel daunted to shave my head as a woman and I am strong and healthy, without the emotional and physical burden of a blood cancer."
This month hundreds of other Illawarra residents will take part in the fundraiser which is in its 21st year, with most events held from March 13 to 17.
More than 12,000 Australians will develop leukaemia, lymphoma or myeloma this year – that's 35 people every day.
Money raised from World's Greatest Shave funds blood cancer research and free support through the Leukaemia Foundation.
"I've wanted to do the Greatest Shave for a while as I see the difference it makes," Ms Tucker said, "helping fund research into new treatments for leukaemia that can change people's lives."
