It's that time of year again when Chicagoans young and old line up to get their heads shaved.
They're raising money for the St. Baldrick's Foundation.
What started out as a challenge between friends has grown into the world's largest fundraising program for childhood cancer research.
But for one college student, she was getting rid of a thick mane of strawberry blonde hair that she dyed pink for fun.
"It's not what's on the head that's important," said. "But what's in the head."
Some of those grabbing razors and shaving heads were young cancer patients themselves.
"It's kind of fun," said one 9-year-old boy.
This is the fifth year the head-shaving event has been held at UIC.
"We're doing it to honor the kids that we take care of everyday," said Dr. Mary Lou Schmidt, a pediatric oncologist.
"And to say thank you to the St. Baldrick’s Foundation for supporting our clinical trials," she added.
