Kieran Moise’s afro was a splendid 19 inches, a huge part of his personality. But after six years of growth, the 17-year-old knew that he and his hair would soon be parted: He was bound for the US Air Force Academy. So, in memory of a friend who died from cancer, he cut it off and donated it to the nonprofit Children With Hair Loss, which provides human hair replacements to children and teenagers facing medically related hair loss. “I knew I didn’t just want it to get cut off and thrown on the floor, so I wanted to give back,” Moise said. He also launched a fundraiser for St. Jude’s Children’s Research Center, which exceeded the boy’s expectations -- he raised $35,000 for the Center. Small gestures of kindness can spread, Moise said. “When you smile, that usually makes someone else smile, and then that one smile can brighten someone else’s day."
