I used to comb the hair of Messenger of Allah ﷺ during my periods. This hadith also reaches us through another chain  

البخاري:٥٩٢٥حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ أَخْبَرَنَا مَالِكٌ عَنِ ابْنِ شِهَابٍ عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ عَنْ عَائِشَةَ ؓ قَالَتْ

كُنْتُ أُرَجِّلُ رَأْسَ رَسُولِ اللَّهِ ﷺ وَأَنَا حَائِضٌ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ أَخْبَرَنَا مَالِكٌ عَنْ هِشَامٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ مِثْلَهُ
