Qualls was born in Nashville, Tennessee, one of five children of Donnie and Debbie Qualls. He was raised in Manchester, Tennessee, and attended school nearby. He was diagnosed with Hodgkin's lymphoma at age fourteen; after two years of treatment, his cancer was said to be in remission. According to Qualls, the chemotherapy at an early age sped up his metabolism and impacted his growth, "It stopped my development," which explains his slender frame. After graduating from Coffee County Central High School, where he was an active member in the Red Raider Band, Qualls attended King's College, London, where he studied English language and English literature. He returned to Tennessee enrolling at Belmont University in Nashville, where he also began acting in a local theater company.
