On Thursday April 11, students and staff at Gawler and District College raised money for the Leukaemia Foundation by shaving their heads or waxing their legs during a lunchtime event.
On top of the head shaves, students could donate five dollars for the privilege of pulling a wax strip from the legs of those who were being waxed.
Mr Mollart also joined in the fun by shaving his beard.
"We had three brave girls shave their heads and hundreds of students come and show their support at the event," a school spokesperson said.
"A big thank you to Jude McColough from Back to Beauty who gave her time to support the event by waxing the boy's legs."
Students and staff managed to raise more than $2000 for the Leukaemia Foundation; with seven shaving their heads, one beard shave and five waxing their legs.
