Many groups have been working in the fight against cancer by doing all sorts of crazy things to raise money.
Many are shaving their heads.
This weekend, it wasn't just the men who decided to shave their heads – women also got involved.
Events like this one have been held across the country for nearly a decade and have raised more than $46 million for the Children's Oncology Group.
