Just over a decade ago, her son Noah was diagnosed with with a rare condition called Proteus syndrome.

Noah lost his battle with the illness in 2012, but on Saturday at Just Cuts, Stockland Shellharbour, his memory lived on.

Two people, Jon Kellyevans and eleven-year-old Sophie Jordan, cut their hair in support of the organisation - Kidzwish Foundation - that helped Noah during his illness.

Ms Southall was there to cut their hair, and said it was a task Noah would have loved to do.

"He would have been ecstatic, he would have loved to do the head shave," she said.

"By working with Kidzwish it means a lot to give back to the community because Kidzwish gave a lot to us and a lot to Noah."

Mr Kellyevans shaved his seven years' worth of hair off, while Sophie cut off her long ponytail.

Following the shave, Mr Kellyevans said he felt "a bit chilly" but was otherwise in good spirits.

"I can't stop touching it .. it's a bit weird but I feel good," he said. "The reason I did it ... everyone was daring me to do it ... and I said if we could raise enough money for charity I would cut it, thinking nobody would and they did. "And then after meeting the Kidzwish people, seeing what they did, it was a no brainer."

All up, Sophie and Mr Kellyevans raised $3,100.

"I feel good after giving my ponytail to someone who would appreciate it more than I would," Sophie said.
