Sahih Muslim Book 24, Hadith Number 5299.

Chapter : It Is forbidden to add false hair to one’s head or to pluck the eyebrow or to separate the teeth.

‘Aisha reported that a woman from the Ansar married her daughter who had lost her hair because of illness. She came to Allah’s Apostle (may peace be upon him) and said: Her husband wants that false hair should be added to her head. Thereupon Allah’s Messenger (may peace be upon him) said: The woman who adds false hair has been cursed. This hadith has been narrated on the authority of Nafi’ with the same chain of transmitters but with a slight variation of wording.
