Kids at Corrimal's Short Street Preschool and Occasional Care Centre have raided their piggy banks to help childcare worker Emma Barrow raise vital funds for the Leukaemia Foundation.
The preschoolers helped a hairdresser cut off Mrs Barrow's long, brunette tresses during the Shave For a Cure event on Monday.
The 28-year-old was able to raise over $2300 for blood cancer research and support, and teach her young charges the meaning of empathy in the process.
"I wanted to get them thinking about the importance of helping people in the community, and they have been really interested in why I decided to do this," Mrs Barrow said.
"They've even made the decision for themselves to help out, with some of them donating their pocket money."
It will take Mrs Barrow a while to get used to her new look, and she said the kids can't stop staring at her.
"One of them came over to reassure me, saying: 'It's all right, it will grow up'."
Meanwhile she's donated her hair to a wigmaker who makes wigs for chemotherapy patients and burns victims.
The tally for this year's World's Greatest Shave is more than $10 million so far, with Gerringong man Matt Fownes the nation's highest fund-raiser with $41,517.
