As of December 2015, Xie Qiuping, a woman from China, holds the record for the world's longest documented hair. Her hair was 18 feet, 5.54 inches long, or 5.267 meters, when measured on May 8, 2004. Quiping was born in 1960, and she started growing out her hair in 1973.
In 2008, Asha Mandela held the Guinness World Record for the world's longest dreadlocks, which were officially measured at 55 feet, 7 inches long. The company retired that particular record in 2009, however, due to the fact that dreadlocks can effectively become hair extensions and therefore, impossible to measure accurately. Tran Van Hay, a man from Vietnam, was thought to have the longest hair in the world prior to his death in 2010, but his hair was never officially measured. His hair was estimated to be just over 22 feet long, or 6.8 meters.
