This week is the traditional 'Go Bald For Baldies week' where people shave off their hair to become bald, to support those who are naturally bald.
We spoke to Victor Baldo - the leader of this year's event - to see why it was a good idea.
"Those who are naturally bald," he said. "Often feel unhappy and alone with the fact that people keep slapping their head. For me, being slapped on the head is like being shot. It is unnecessary and hurtful - just think about the bald person's feelings.
Many celebrities are also getting involved in the 'Get bald for Baldies week' with Britney Spears and Russell Brand shaving off their hair for the week. However Britney may not have done it for charity.
