Sharon Shaw and Vanessa Warren have been friends for more than four years and when one sets up a challenge, the other does not bow down.
That is what happened a week ago, when Ms Shaw said she would shave her hair completely if her Relay for Life Remarkable Red team raised $1000 more than its initial goal.
Ms Warren then challenged the team to raise $2000 "over and above" and she would do the same.
"My friends are going to donate plenty, because they want to see me bald," Ms Warren said.
Three years ago her father died of bowel cancer and only five days later Ms Shaw's mother died within 10 days of being diagnosed with pancreatic cancer.
"I think everyone knows somebody who has had cancer," Ms Warren said.
The two Warehouse employees are taking part in their first Relay For Life event this year and are members of a 10-person Warehouse team which hopes to raise $3000.
The Cancer Society Relay for Life celebrates and acknowledges cancer survivors and also remembers loved ones who have died.
The Relay for Life Cromwell event is to be held on March 17-18 at the Cromwell racecourse, where more than 60 teams will walk for 24 hours to raise money for cancer research and support.
Ms Warren is not a bit worried about losing her locks.
In fact, she will be disappointed if she has hair after the March 10 cut-off date, although she has reservations about Queenstown's autumn and winter temperatures.
"It might be cold, especially when it frosts."
"My son was a bit shocked," Ms Shaw said.
"People with cancer and who are going through chemotherapy don't have the choice to lose their hair, but this is my choice."
Ms Shaw admitted to some anxiety about the dramatic change likely to be in store.
"At this stage I cannot say I won't cry when it happens."
"I'm nervous about that bit, but I am 100% going through with it."
"The motivation is the family we have lost and it is a small price to pay. Touch wood, but we still have good health."
Ms Shaw pointed out hair never grew back the same at her age.
"I'm going grey, so I am a bit concerned when it comes back that it'll be completely grey."
