Women's hair may be hidden using headscarves, a common part of the hijab in Islam and a symbol of modesty required for certain religious rituals in Orthodox Christianity. Orthodox Judaism endorses the use of wigs, scarves and other headcoverings for women for modesty reasons as in Islam. Hassidic Judaism, on the other hand, discourages the trimming of head hair, and male practitioners typically wear their hair in ringlets (peyos). Sikhs generally keep their hair uncut and men keep it tied in a bun on the head, which is then covered appropriately using a turban.
