Nancy Moore has gotten pretty good at cutting hair over the last 30 years as a professional barber.

So the Richmond Hill mom had no problems picking up her clippers again on Saturday for a good cause that hit a little close to home. Moore was one of the dozens of volunteers clipping hair to support cancer research at the annual Savannah St. Baldrick's fundraiser in City Market.

Moore's 15-year-old son, Dylan, was diagnosed with a rare form of leukemia in 2010.

"It's amazing to see people come out and support and get their heads shaved," Moore said. "It reminds me of when everyone was being so supportive of him. Now, he's a survivor. So we come to help out every year."

The buzzing sound of clippers permeated throughout City Market as volunteers and spectators lined up to see people "keep calm and go bald" for the cause.

The event raises money for childhood cancer research, which is the most underfunded facet of cancer research, said Yael Elfassy,the volunteer event organizer in charge of Savannah's St. Baldrick's.

"The event helps us to raise awareness and usually raises anywhere between $20,000 and $40,000," Elfassy said. "And everything is volunteer- from the barbers to the participants to me. It's all about helping out. Childhood cancer is the most underfunded in cancer research. Only about 4 percent of money at the National Cancer Institute goes toward childhood cancer research."

The St. Baldrick's Foundation is a national organization that started in 2000. Officials hosted the first St. Baldrick's event in a New York pub with a goal of shaving 17 heads and raising $17,000.

That number was quickly surpassed. At the first annual St. Baldrick's event, 19 heads were shaved and $104,000 was donated to Children's Oncology Group, a leader in childhood cancer research.

The event grew quickly and now takes place in 45 states across the U.S., as well as the United Kingdom, Thailand, China and Grenada. And St. Baldrick's is now the second largest supporter of childhood cancer research, according to Elfassy.

Among Saturday's shavees was Carol Malazita and her husband, Al, visitors from Pennsylvania and veteran St. Baldrick's participants.

"This is my sixth year shaving my head," said Carol Malazita. " I keep coming back because its important to support the children. I was a teacher for 36 years, and I've had students die from terrible illnesses. It's a very important cause for us to support."

More than $52,000 was raised during the event.

Father and daughter duo Rickey and Rebecca Neidlinger from Effingham County raised more than $15,000 for cancer research before shaving their heads Saturday.

"It's a small sacrifice," said Rickey Neidlinger. "We're here to support my niece Ella Bothwell and the kids around our area who are fighting."
