Is it obligatory for a woman to undo her hair when she performs ghusl for menstruation or major ritual impurity?

Question:
Honorable Shaykh, may Allah grant you success. This is a woman asking, and she says: Is it obligatory for a woman to undo her hair when she performs ghusl for menstruation, and when she performs ghusl for major ritual impurity?

Answer:
For ghusl from major ritual impurity, no, it is not obligatory for her, as that is difficult for her. But when she performs ghusl for menstruation or post-natal bleeding, she must undo it. Yes.
