Musannaf Ibn Abi Shaybah 798 — A woman performing ghusl: does she undo

Ubayd bin Umayr said: Sayyidah Aishah (may Allah be pleased with her) was informed that Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) orders women to undo their braids for the ritual bath. Sayyidah Aishah (may Allah be pleased with her) said: "How strange of Ibn Amr! Why does he not order them to shave their heads? The Messenger of Allah (peace and blessings be upon him) and I used to bathe from a single vessel, and I would not pour water over my head more than three times."
