There were clippers, hair and tears at a Whanganui Intermediate School assembly last week.
Students Charli Wood and Emma Collins joined forces to take part in Leukaemia & Blood Cancer New Zealand's signature fundraising event, Shave for a Cure.
Supportive students watched on as proud parents shaved their daughters' heads and their teacher Brylee Kemp said things got emotional.
"Charli was crying, I don't think it was because she was upset, it was more because it was such a big thing that they were doing," Kemp said.
"Everyone was so proud of them."
