IT started as a bet, two years ago between two sisters at Nimmitabel.
Mae Walker's older sister bet $10 that she would never shave her head after they had seen a 14 year-old girl shave her head to raise money for the 40 hour famine on Facebook.
Mae said she wouldn't care about her appearance and that she would be able to do that.
Her sister bet that she wouldn't.
At 11-years-old Mae took up her sister's challenge.
A few months shy of 14 (her 14th birthday is this May), she is taking the clippers to her head to raise money for the Leukemia Foundation.
Her hair, which she has been growing as long as possible over the past two years in anticipation of the shave and that she can now sit on, will be donated to Ascot Wigmakers in Sydney who specialise in making wigs for accident and burns victims, alopecia sufferers and chemotherapy patients.
She had planned to do the shave when she was 14 but couldn't wait.
"I'm sick of having long hair," she said.
"I wish it was sooner, I'm sick of having it. It's making me incredibly hot."
Mae will have her head shaved on the main stage in front of a large crowd at the Canberra Show on Friday 22 at 3pm.
She says she isn't nervous about being bald, and that she is looking forward to getting rid of her long locks.
It will grow back after all.
She is hoping to raise $250 and is almost there, having raised $180.
