Musannaf Ibn Abi Shayba 16:997

Abu Bakr narrated to us, he said: Yahya ibn Abi Bukayr narrated to us, from Shu'bah, from 'Amr ibn Murrah, he said: I heard al-Hasan narrating from Safiyyah bint Shaybah, from 'Aishah, that a young woman from the Ansar got married. She became ill and her hair fell out, so they wanted to add hair extensions to it. They asked the Messenger of Allah (peace and blessings of Allah be upon him) about that, and he cursed the woman who adds hair extensions and the woman who asks for them to be added.
