How does a woman purify herself after menstruation, and is there a specific remembrance (dhikr) to be recited during purification?

When a woman sees one of the two signs of purity (the white discharge or dryness of the area), she must perform ghusl (definition) (ritual bath) and pray. The ghusl from menstruation is like the ghusl from janabah (definition) (ritual impurity), and its description is: washing the hands, then washing the private parts, then performing ablution (wudu'), then ensuring water reaches the roots of the hair (without undoing the hair), pouring three handfuls of water over the head, then pouring water over the rest of the body, and finally washing the feet. It is recommended to say "Bismillah" (In the name of Allah) at the beginning of the ghusl.
