Ben Brown will shave off his famous head of hair at Melbourne's 2023 family day to raise awareness and funds for children living with cancer.

Brown has a personal link to the disease, speaking about his young cousin Grace's battle with leukaemia as he urged people to donate if they are able. Grace was first diagnosed when she was just six years old.

The hair transformation will take place on February 25 at Yarra Park, with the Demons encouraging families and fans to come along.

“Any help that all of you can give me along that journey, knowing what this girl has gone through and what my family's gone through would mean the world to me,” Brown said.

“Grace had a pretty tough time of it throughout her life… when she was six, she was diagnosed with leukaemia.

“She has gone through many years of treatments, many years in the hospital, had a few years of everything's all great and then had a relapse and was diagnosed with leukaemia again.

“Fortunately, Grace is in remission again for a second time following some amazing new technology that's come through called CAR T-cell therapy."

Brown, who made his AFL debut in 2014, admitted that he hasn't cut his hair in ten years.

All proceeds will go towards the Challenge organisation, a non-profit supporting kids with cancer.
