Whenever the Prophet ﷺ took the bath of Janaba (sexual relation or wet dream) he asked for the Hilab or some other scent. He used to take it in his hand, rub it first over the right side of his head and then over the left and then rub the middle of his head with both hands.
كَانَ النَّبِيُّ ﷺ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ دَعَا بِشَىْءٍ نَحْوَ الْحِلاَبِ فَأَخَذَ بِكَفِّهِ فَبَدَأَ بِشِقِّ رَأْسِهِ الأَيْمَنِ ثُمَّ الأَيْسَرِ فَقَالَ بِهِمَا عَلَى رَأْسِهِ
When the Messenger of Allah ﷺ took a bath because of sexual intercourse, he called for a vessel and took a handful of water from it and first (washed) the right side of his head, then left, and then took a handful (of water) and poured it on his head.
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ دَعَا بِشَىْءٍ نَحْوَ الْحِلاَبِ فَأَخَذَ بِكَفِّهِ بَدَأَ بِشِقِّ رَأْسِهِ الأَيْمَنِ ثُمَّ الأَيْسَرِ ثُمَّ أَخَذَ بِكَفَّيْهِ فَقَالَ بِهِمَا عَلَى رَأْسِهِ
"When the Messenger of Allah ﷺ performed Ghusl from Janabah, he would call for something like a vessel used for milking a she-camel, then he would take (some water) in his hand and start with the right side of his head, then the left, then take (some water) in his hands and start pouring it on his head."
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ دَعَا بِشَىْءٍ نَحْوِ الْحِلاَبِ فَأَخَذَ بِكَفِّهِ بَدَأَ بِشِقِّ رَأْسِهِ الأَيْمَنِ ثُمَّ الأَيْسَرِ ثُمَّ أَخَذَ بِكَفَّيْهِ فَقَالَ بِهِمَا عَلَى رَأْسِهِ
when the Messenger of Allah (May peace be upon him) wanted to wash himself because of sexual defilement, he called for a vessel like HILAB (a vessel used for milking the camel). He then took a handful of water and began to pour it on the right side of his head and then on the left side. He then took water in both his hands together and poured it on his head.
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ دَعَا بِشَىْءٍ نَحْوِ الْحِلاَبِ فَأَخَذَ بِكَفِّهِ فَبَدَأَ بِشِقِّ رَأْسِهِ الأَيْمَنِ ثُمَّ الأَيْسَرِ ثُمَّ أَخَذَ بِكَفَّيْهِ فَقَالَ بِهِمَا عَلَى رَأْسِهِ
