Xie Qiuping has the longest hair in the world. Her hair is over five meters long. How can hair grow so long? Hair grows from a small tube under your skin. This tube is called a follicle. Inside the tube, special cells make the hair. The hair comes out of the skin and gets longer. Hair on your head grows about 15 centimeters every year. Most hair grows for five to seven years.
