Understanding Turbans explains the various turbans, from those worn by Sikhs, to the kaffiyeh worn by many Arabs, to the exotic turbans worn in the deserts of Africa:
Sikh men commonly wear a peaked turban that serves partly to cover their long hair, which is never cut out of respect for God’s creation. Devout Sikhs also do not cut their beards, so many Sikh men comb out their facial hair and then twist and tuck it up into their turbans along with the hair from their heads. Sikhism originated in northern India and Pakistan in the 15th century and is one of the youngest of the world’s monotheistic religions.
