After hearing a member of their family was being rushed in for emergency brain surgery, four men broke out the clippers in a sign of solidarity.
Aidan Bunker, from Great Linford, had an abscess in the sinus which leaked into his brain, prompting the surgery at John Radcliffe Hospital in Oxford.
The 17-year-old was concerned before the surgery, not only for his safety, but about his hair.
So in support, Martin, Ben Couzens, Dan Fassett and Phil Kerridge called on Giuseppe Frasca to shave their heads.
They also raised sponsorship money -almost £1,700 in fact - for the John Radcliffe Hospitals Charitable Funds for being so supportive of Aidan after his surgery.
