At age 44, Xie Qiuping cut her hair for the first time in over three decades. Her impressive locks extended over 5 meters — earning the Guinness World Record for the world’s longest hair. But even with this record-setting feat, her hair might not have reached its maximum possible length. So, just how long can human hair actually grow? Maksim Plikus digs into what factors influence hair growth. \[Directed by Matt Partridge, narrated by Jack Cutmore-Scott, music by Thomas Bell\].
