Musannaf Ibn Abi Shaybah 803 — A woman performing ghusl: does she undo

Sayyidah Umm Salamah (may Allah be pleased with her) said that she asked the Messenger of Allah (peace and blessings be upon him): "I am a woman who braids my hair tightly; what should I do when I take the ritual bath (ghusl)?" The Prophet (peace and blessings be upon him) said: "Pour three handfuls of water over your head, then after each handful drench it thoroughly with water."
