"In Sikhism, Kesh (sometimes Kes) is the practice of allowing one's hair to grow naturally as a symbol of respect for the perfection of God's creation. The practice is one of the Five Ks, the outward symbols ordered by Guru Gobind Singh in 1699 as a means to profess the Sikh faith. The hair is combed twice daily with a Kanga, another of the Five Ks, and tied into a simple knot known as a Joora, or Rishi knot. This knot of hair is usually held in place with the Kanga and covered by a turban."
