Red Dot on woman's forehead

I am doing a project for school and I could you some help. Is the "red dot" on some women's foreheads related to Islam and if so how?.

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

The red dot, which some women place on their foreheads specially in India, has nothing to do with Islam. It is an Indian custom, we were told, Hindu women wear the red dot to imply being married. We were also told that other peoples of India do imitate the Hindus.

We ask Allaah to show the righteous path.
