A group of Sydney schoolgirls is a cut above their peers after chopping off their ponytails for charity.
About 40 girls at Wenona School willingly had their locks snipped off on Wednesday by volunteer TAFE NSW hairdressing teachers.
The hair will be used for medical wigs for people with cancer or alopecia.
The students from the North Sydney school each donated at least 15 centimetres to waste recovery business Sustainable Salons Australia (SSA) - the largest provider of ponytails to children's charity Variety.
Former Wenona student Miranda Ilchef founded the event in 2015 after watching her aunt lose her hair from chemotherapy treatment for breast cancer.
"I noticed that it (a wig) helped her restore a sense of normality in what is a very abnormal procedure," Ms Ilchef told AAP.
"Hair grows for free ... so I think it's a small thing we can do to make a big difference in someone else's life," she said.
Wenona's school theatre was abuzz on Wednesday as the hair donations began to stack up. Student event organisers Xanthe Muston and Charlotte Doughty both significantly trimmed their tresses.
SSA managing director Paul Frasca said the school's annual charity gig contributed to the 10,000 ponytails collected last year.
"Your hair is so vital in making sure there is enough supply to make the medical wigs," he said.
"You don't realise how much you miss hair until you don't have any hair."
A number of other schools have expressed interest in holding a similar event and SSA plans to take it "as far as it can go", Ms Ilchef said.
