80-year-old Luo Shiyuan wears his 2-meter-long hair over head at a wild animal zoo in southwest China's Chongqing Municipality Wednesday, September 27, 2006. Luo, who lives in a remote mountain in Chongqing, has been growing his hair and beard for 30 years, which stand at 2 meters and 1.5 meters long respectively. With his grey and unkempt hair, Luo is hailed as a wild man.
In 2006, the villagers spent 5 hours helping him to wash his hair using 3 giant packs of detergen after failing to wash his hair using 6 bottles of shampoo.
I've seen some people who doesn't take any bath before and the smell is pretty horrible.
