K's are signs of Khalsa Sikhism
Khalsa Sikhism has five elements: 5 K's which are the things Sikhs wear at all times. They are:
- Having unshorn/cut hair. This is called Kes. One must, whether male or female, is required to keep their Kes covered, whether it be in the form of a turban, bandana, or a scarf (Chunni)
- Having a wooden comb in their hair. This is called Kangha. This symbolizes cleanliness which is an important part of Sikhism.
