Musnad Ahmad 1153:787

Aswad narrated to us, he said: Sharik narrated to us, from Hisham, from his wife Fatimah, from Asma bint Abi Bakr, that a woman came to the Prophet, may God bless him and grant him peace, and said: "I have a daughter who is a bride, and she became ill, so her hair fell out. Should I attach hair to it?" The Prophet, may God bless him and grant him peace, said: "God has cursed the one who attaches hair and the one who asks for it to be attached."
