A bindi is a small dot or sticker worn on the center of the forehead, originally by Hindus, Jains, Buddhists, and Sikhs from the Indian subcontinent). The term "bindi" comes from the Sanskrit word "bindú" meaning "point, drop, dot or small particle"). The bindi is traditionally red and circular, but it can come in different colors, shapes, and sizes. It is worn by women of all religious dispositions in South Asia and is not restricted to religion or region). However, the Islamic Research Foundation, located in India, says "wearing a bindi or mangalsutra is a sign of Hindu women").

The red bindi has multiple meanings. One simple interpretation is that it is a cosmetic mark used to enhance beauty). The bindi also has religious and symbolic roles. It can serve as a reminder to its wearer to keep God at the center of her thoughts. A red bindi also serves as a sign of marriage, guaranteeing a wedded woman the blessings and social status of the institution. In some cultures, if a woman becomes a widow, she either replaces the red bindi with a black one or a dash of white ash or stops wearing a bindi altogether. Some women remove their bindis when mourning any family member.

In addition to the bindi, in India, a vermilion mark in the parting of the hair just above the forehead is worn by married women as a sign of their marital status).

The bindi has also become popular among women of all ages as a beauty mark. In fact, a new campaign from the Neelvasant Medical Foundation and Research Centre, a nonprofit based in Nashik, India, has come up with a way to coat the back of bindis with iodine to help women and babies stay healthy.
