But today, more than 30 girls will cut their hair in the Pit.
And instead of being swept into a dustpan, the hair will be made into wigs through the Locks of Love organization for children who have lost their hair.
"Many patients suffer from alopecia, a disease causing the loss of hair," said Kathleen Cason, Locks of Love spokeswoman. "There are different types of the disorder, but there is often a complete loss of all body hair."
Locks of Love collects human hair donations of 10 inches or longer and makes wigs customized for each recipient.
Most of the female patients want hair of at least 8 inches long. With 10-inch to 12-inch donations, that leaves room for the manufacturing process.
Hair separated from the long donations is made into shorter pieces for male recipients.
"The wigs are generally given free of charge, though such hairpieces sell for as much as $3,000 on the market," Carson said.
If donations shorter than the 10-inch requirement are submitted, the organizations sells them and uses the money to offset production of the wigs.
"This is an amazing way to donate to a good cause in a different way," said senior Liz Crowley, an organizer of Friday's event. "This is a great way to do a little more to help."
