For Sikhs, a turban, known as a pagg or dastar, is a religious object. It’s their most identifiable feature and is primarily used as such—a way for other people to recognize them. It’s worn by both Sikh women and men as a symbol of equality, and as a method of hair protection and cleanliness. Similarly, members of the Rastafarian religion may use turbans as a way to protect their dreadlocks. In Bitch Magazine, Rachel Charlene Lewis writes about the sleep bonnet, a turban-like cap, often lined in silk or satin, that black women have long worn to protect their hair at night. The sleep bonnet isn’t just about hair care though; it’s also rooted in racist laws that required black women to cover their hair in public, and persistent discrimination against natural hair.
