Six children are "braving the shave" to fight childhood cancer.
The kids will donate a combined total of about 50 inches of hair, which will be used to make wigs for cancer patients.
Team Captain Hannah Thinnes has a special reason for organizing the team.
Hannah's sister Mia was diagnosed with brain cancer in 2010.
"My sister had brain cancer and I cut my hair right after she was diagnosed. And then this will be my second time cutting my hair," says Hannah Thinnes.
Mia says she thinks it's cool that people donate their hair, and she plans to donate her own hair when it is long enough.
"I want to donate my hair because it feels great if you do stuff like that. And I want to have the opportunity to do that," says Mia Thinnes.
The annual Brave the Shave event benefits Pantene Beautiful Lengths and the St. Baldrick's Foundation- a childhood cancer charity.
Hannah will be donating eight inches of her hair.
So far, they have raised more than 600 dollars.
