The Prophet ﷺ said, "Allah has cursed the lady who artificially lengthens (her or someone else's) hair and the one who gets her hair lengthened and the One who tattoos (herself or someone else) and the one who gets herself tattooed"
عَنِ النَّبِيِّ ﷺ قَالَ لَعَنَ اللَّهُ الْوَاصِلَةَ وَالْمُسْتَوْصِلَةَ وَالْوَاشِمَةَ وَالْمُسْتَوْشِمَةَ
