Two or three feet of dirty hair?
Hair, yes. Dirty, no.
I worked with a Sikh engineer once.
On weekdays he wore his turban and a suit and tie.
On weekends, when he came to work, he wore a linen robe of some sort and no turban.
His beard and hair would nearly touch the floor, and he was at least six feet tall or better.
Every morning he would roll up his beard and hair into some type of ritualistic weave and wrap his turban into it and upon his head..........
As to the ‘knife’ comment that would be on his belt, but mostly they have ceremonial knives that are just for show...........
