For the Malone sisters, the pain of losing a family member to cancer is an all too familiar feeling.
The trio of Macarthur siblings lost their beloved dad, Wayne Malone, to Leukaemia just six weeks ago.
Now they plan to take part in the World's Greatest Shave with a special event to be held at the Ambarvale Hotel on Saturday, March 13.
Melissa Woodward (nee Malone) said her father's nine-month battle with the disease inspired them to get involved.
"We received an email from the Leukaemia Foundation about the World's Greatest Shave and my youngest sister suggested we get involved," the Ruse resident said.
"I took my time before committing to make sure that I was doing it to feel brave and empowered.
"I did not want to do it fuelled by grief and have regrets.
"It's going to be an amazing atmosphere of love and support in the room and being able to band together as a family to do this has helped make the decision easier to go ahead."
Ms Woodward, who has never had her hair shorter than chin length, will brave the shave alongside her sisters Kerrianne Morgan of Tahmoor and Campbelltown's Amanda Malone.
Their family friend Janet Kingston will also shave her head while their mum Janelle Leggett will colour her hair for the cause.
Ms Morgan's daughter, Clair Malone, will also chop off a large portion of her hair to raise funds.
"We have set a team goal of $10,000 but I would love to go well beyond that," Ms Woodward said.
"The Leukaemia Foundation sent us info about how the money will help and $10,000 will provide emotional support to 300 families to help them overcome the initial shock and stress of being diagnosed."
Ms Woodward said that feeling was one she knew well.
"We remember the initial shock and uncertainty of the early days," she said.
"We were a strong family who banded together to have Dad at every single test and appointment at Liverpool Hospital.
"His doctors said they were inspired by the fact that Dad was never alone in the waiting room.
"Not every family can do that so we hope that by raising funds, we are able to provide practical support like accommodation and counselling for other families to be able to be there for their loved ones."
Ms Woodward encouraged everyone to come along to the family friendly event.
"Our event is going to be a fun-filled day with loads of raffle prizes and silent auction items generously donated by local businesses," she said.
"We have the very funny and down to earth Ally Redondo joining us to host the event.
"It's free to attend. We wanted to create an accessible, kid-friendly event where people could come along to support us no matter whether they can donate a little or a lot.
"We would really love to thank the Macarthur community and businesses that have supported us through donations and raffle prizes.
"We are truly grateful and blown away by the support."
