It is recommended to apply perfume just before entering Ihram, and it is recommended to use Musk, and it does not matter if its glistening traces remain Sahih Muslim 1190 e
Arabic hadith text
وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، قَالَ سَمِعْتُ إِبْرَاهِيمَ، يُحَدِّثُ عَنِ الأَسْوَدِ، عَنْ عَائِشَةَ، - رضى الله عنها - أَنَّهَا قَالَتْكَأَنَّمَا أَنْظُرُ إِلَى وَبِيصِ الطِّيبِ فِي مَفَارِقِ رَسُولِ اللَّهِ صلى الله عليه وسلم وَهُوَ مُحْرِمٌ .
Translation
'A'isha (Allah be pleased with her) said
I still seem to see the glistening of the perfume where the hair was parted on Allah's Messeinger's (ﷺ) head while he was in the state of Ihram.
