After growing his hair out for four years, Tonight Alive guitarist Jake Hardy has shaved his head for the Leukaemia Foundation's World's Greatest Shave. You can watch a video of frontwoman Jenna McDougall helping him out below.

Hardy is on a mission to raise $10,000 dollars for the foundation, and has already amassed nearly $4,000. If he reached his goal, he'll wax his chest. Make sure you do your part and help him out.
