LOUISVILLE, Ky. (WDRB) -- They've all been touched in some way.

"My mom was diagnosed with breast cancer 5 years ago, and she's a 5-year cancer survivor," says Sarah Anderson.

"Dawson was diagnosed with 7 brain and 3 spinal tumors when he was 6-months-old," says Aimee Barr.

Dawson Barr went through 5 years of chemo at Kosair Children's Hospital.

He's now been off treatment for 2 years.

"He does still have one tumor remaining on his brain. It does affect his vision. He is legally blind because of where his tumor is at. But he functions very well," says Aimee Barr.

He's the prime example of why people joined together on Sunday to do their part to help the St. Baldrick's Foundation, and kids affected by cancer.

"One of the great things about this foundation is it raises more money and provides more grants than anybody else in this area of pediatric cancer care than the federal government," says Dr. David Dunn, Vice-President for Health Affairs at U of L.

"We have got to find a cure for this beast. We have got to wipe this out. No parent should ever hear, 'your child has cancer'," says Aimee Barr.  

So, with the help of this electric razor, people sacrificed their hair to raise awareness and money.

One by one, we watched dozens of people go bald: Dr. David Dunn, U of L Executive Vice President for Health Affairs, children, and even adults.

They were all willing to part with their hair to fight back.

"I think it's cool how other people, like girls that have long hair, I think it's cool how they donate their hair," says Dawson Barr.

Aimee Barr says watching people sacrifice their time, money, and looks, to bring awareness to this issue means the world.

"It's very emotional. I cry every year," says Aimee Barr.  

Supporters say money raised will not only fund the cancer research taking place nationally, but locally as well, so that children like Dawson, will benefit.

"This money will come back in part to the University of Louisville Department of Pediatrics for our great researchers and caregivers there," says Dr. Dunn.

Over the years, more than 4,000 people locally have participated in the head-shaving event.

Nationally. more than 125 million dollars has been raised for this foundation and cancer research.
