An Ansari woman gave her daughter in marriage and the hair of the latter started falling out. The Ansari women came to the Prophet ﷺ and mentioned that to him and said, "Her (my daughter's) husband suggested that I should let her wear false hair." The Prophet ﷺ said, "No, (don't do that) for Allah sends His curses upon such ladies who lengthen their hair artificially."  

أَنَّ امْرَأَةً مِنَ الأَنْصَارِ زَوَّجَتِ ابْنَتَهَا فَتَمَعَّطَ شَعَرُ رَأْسِهَا فَجَاءَتْ إِلَى النَّبِيِّ ﷺ فَذَكَرَتْ ذَلِكَ لَهُ فَقَالَتْ إِنَّ زَوْجَهَا أَمَرَنِي أَنْ أَصِلَ فِي شَعَرِهَا فَقَالَ لاَ إِنَّهُ قَدْ لُعِنَ الْمُوصِلاَتُ
