"I said: 'O Messenger of Allah, I am a woman with tightly braided hair; should I undo it when performing Ghusl from Janabah?' He said: 'No it is sufficient for you to pour three handfuls of water over your body.'" (Using translation from Nasāʾī 241)
عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ قَالَتْ قُلْتُ يَا رَسُولَ اللهِ إِنِّي امْرَأَةٌ شَدِيدَةُ ضَفْرِ رَأْسِي أَفَأَنْقُضُهُ عِنْدَ غَسْلِهِا مِنَ الْجَنَابَةِ؟ قَالَ «إِنَّمَا يَكْفِيكِ أَنْ تَحْفِنِي عَلَى رَأْسِكِ ثَلَاثَ حَفَنَاتٍ مِنْ مَاءٍ ثُمَّ تُفِيضِي عَلَى جَسَدِكِ»
