Narrated Asma: (the daughter of Abu' Bakr) A woman came to Allah's Apostle and said, I married my daughter to someone, but she became sick and all her hair fell out, and (because of that) her husband does not like her. May I let her use false hair? On that the Prophet cursed such a lady as artificially lengthening (her or someone else's) hair or got her hair lengthened artificially.
