Allah's Messenger (ﷺ) has cursed the lady who uses false hair.
Sahih al-Bukhari Book 65, Hadith 407
← Previous Hadith `Abdullah (bin Masud) said. "Allah curses those ladies who practice tattooing and those who get themselves tattooed, and those ladies who remove the hair from their faces and those who make artificial spaces between their teeth in order to look more beautiful whereby they change Allah's creation." His saying reached a lady from Bani Asd called Um Yaqub who came (to `Abdullah) and said, "I have come to know that you have cursed such-and-such (ladies)?" He replied, "Why should I not curse these whom Allah's Messenger (ﷺ) has cursed and who are (cursed) in Allah's Book!" Um Yaqub said, "I have read the whole Qur'an, but I did not find in it what you say." He said, "Verily, if you have read it (i.e. the Qur'an), you have found it. Didn't you read: 'And whatsoever the Apostle gives you take it and whatsoever he forbids you, you abstain (from it). (59.7) She replied, "Yes, I did," He said, "Verily, Allah's Messenger (ﷺ) forbade such things." "She said, "But I see your wife doing these things?" He said, "Go and watch her." She went and watched her but could not see anything in support of her statement. On that he said, "If my wife was as you thought, I would not keep her in my company."
