Beard, who played 35 first-class games for Otago between 2009 and 2015, has set up a web page to raise $3000 for Camp Quality New Zealand.
The charity runs camps for children affected by cancer.
"It costs Camp Quality $3000 per year for each child to come to camp and so I’m doing my bit to help," Beard wrote on the page.
"I have teamed up with five of the lads from the Otago Volts — Hamish Rutherford, Mark Craig, Jimmy Neesham, Brad Wilson and Christi Viljoen.
"We will be shaving our heads at the top of Baldwin St ... for the cause."
Beard, who now works in real estate, said "working in the real world" has helped "open his eyes".
"I’ve been fortunate enough to have had a pretty good start in life and I just want to give back to people who are not as fortunate as myself."
A tentative date of October 28 has been pencilled in but the shavers may have to be put on hold depending on the availability of the players.
Some of the Volts have more hair to lose than others. One female donator commented it was a great cause but she would miss Neesham’s locks.
