Question:
Is it sufficient for a woman, when performing the full ritual bath for major ritual impurity, to pass water through her hair without rubbing it?

Answer:
In the case of major ritual impurity, she lets the water flow over it and ensures it reaches the hair, provided she does not untangle it. Untangling is only for the menstruating woman and the woman with post-natal bleeding; she untangles it if it is visible, for menstruation and post-natal bleeding. As for major ritual impurity, she does not untangle it; she lets the water flow over it and ensures it reaches the hair. If she uses rubbing, that is more cautious and better. Yes.
