Children watch in awe and adults hold back tears as young Molly Healy loses her thick brown locks with a beaming smile.
The six-year-old Upper Swan Primary student may be one of the school's youngest students, but her consideration for others reaches beyond her years.
When her hair fell to the floor in front of her classmates this week, she dedicated her dramatic gesture to a little girl she barely knew.
Robyne Healy said her daughter was influenced by TV advertisements for the World's Greatest Shave. She returned from school days later with a plan to dedicate her shave to a Year 1 student who died last year.
Charlotte Peachey was only six when she died from an inoperable brain tumour. She is remembered fondly at the school.
"Molly came home one day and said I'm going to shave my head for Charlotte and her family now," Ms Healy said.
She said she had been touched by her daughter's gesture and agreed to shave her hair for her this week.
"She is thoughtful . . . she has already told me that she wants to be a doctor and help kids and animals," she said.
Through her school and a Facebook page, Molly raised more than $200 for the Leukaemia Foundation.
She is one thousands of West Australians expected to raise almost $3 million as part of World's Greatest Shave events.
