You may have seen my earlier post about the significance of Kesh (uncut hair) in other cultures. Here's the link: http://ambrosialnectar.blogspot.com/2011/01/kesh-unshorn-hair.html
So I thought I should mention something about the dastaar. We all know than in India Hindus and Muslims wore, and still wear, a turban as either a symbol of royalty or a symbol of saintliness. In other cultures a turban-like headdress can be worn as protection from the heat or just as cultural clothing.
What I found interesting was that the Bobo Shanti branch of the Rastafarian movement cover their dreadlocks with a dastaar as their religious identity. I won't bother going into it (it's worth researching) but here are some pictures.
Note: None of these pictures are mine (all taken from searching 'Bobo Shanti' on google images)
