More than $109,000 has been raised for the Leukaemia Foundation as a show of solidarity for Murray Bridge boy Oscar Noye, who is battling the blood cancer.
What started with his father, Josh, aiming to raise $5000 by shaving his head grew to 55 people across the country shaving, cutting or colouring their hair in support of the two-year-old, including three people who got so caught up in the event that they decided on the day that they would join in.
Josh said he felt a real sense of community on Sunday, July 5, not only at the Oakbank Hotel, where most of the shaves took place, but from everyone who had donated or supported the cause.
"Before we started, it ticked over $100,000, and everyone was on a high from that," he said.
"We're super happy with how it went. We feel so blessed and loved by everyone around us."
Oscar helped with some of the shaves, including his dad's, with guidance from his mother Amelia.
Hairdressers from Elite Barbers and Zavesti Hair and Body, as well as other family friends, were present to make sure the shaves and cuts were tidy.
Dr Martin Altmann, who delivered Oscar and has been his doctor ever since, raised the most funds individually, with more than $11,000.
The second-highest fundraiser was Hawthorn Football Club player and good friend Chad Wingard, who ran a raffle of a team signed guernsey and match-worn boots for anyone who donated $20 or more.
Josh said Oscar had "a heap of fun" on Sunday before starting the third phase of his treatment on Tuesday.
