CAROLYNNE May and David Lea will lop their locks for the first time this weekend - to raise money for a cause close to their hearts.
Mr Lea's daughter Kira Matthews, 17, was diagnosed with a tumorous cancer in July 2013 and in November last year was given six months to live.
He said it was a difficult time for his family.
"We are trying to get her to her 18th birthday in August but we are not quite sure how she will go," he said.
"I have lots of sleepless nights.
"Sometimes I don't want to go to work at all."
Mr Lea said this year was the first time he would participate in the World's Greatest Shave.
"I want to raise awareness and money for people with cancer," he said.
Meanwhile Ms May is already regretting her decision to shave her head for a cure.
Ms May was having skin cancer on her scalp removed anyway and her daughter suggested she should should shave all her hair off in the process.
But now, the thought of cutting off her much-loved hair is almost too much.
"I'll be going full bald to raise money for charity," she said.
"I was going to have a bit of my hair shaved off anyway because of the cancer and I guess it's all or nothing now.
"It's very scary, because I love my hair, but my mum had cancer, my nan had cancer, as did my cousin so it means something to me."
All money raised will go towards the World's Greatest Shave, which raises money for the Leukaemia Foundation to fund research and support for those with blood cancer.
Ms May will shave her hair at Heidi for Hair, Strathfieldsaye, on March 16 at 1.30 while Mr Lea will shave his on Saturday at Lansell Square about 11am.
