Students from Girton Grammar's junior school shaved their heads to rise money and awareness for the Leukaemia Foundation this week.
Twenty students, including two girls and a female teacher braved the shave to take part in the fundraiser.
Deputy head of junior school Viv Bath is a passionate advocate of the event.
"Girton has a long history of raising money and awareness through World's Greatest Shave.
"Both our senior and junior school students and staff have supported this event for fourteen years," Mrs Bath said.
Students who didn't take part in the shave were able to play their part with crazy and colourful hairstyles.
Last year, more than $35,000 was raised by the school.
"It is quite moving to watch young children pledge their commitment to supporting leukaemia research in such a personal way," Mrs Bath said.
Jools for Jim hairdressing donated their time and hairdressers for the event.
World's Greatest Shave aims to raise $16.5 million nationwide this year and is celebrating its 22nd year.
The money raised for the Leukaemia Foundation will go towards their goal of ensuring there are zero lives lost to blood cancer by 2035.
Blood cancer is one of the top four most frequently diagnosed caners and a leading cause of death by cancer in Australia.
Every day, 41 Australians are told they have blood cancer and 20 people lose their lives daily.
