Amr bin Suwaid (may Allah have mercy on him) says that once the issue of applying perfume in the state of Ihram was being discussed in front of Aisha bint Talha. She narrated that Umm al-Mu'mineen Hazrat Aisha (may Allah be pleased with her) said that she traveled with the Prophet (peace be upon him). She had her hair stuck together and had tied this band before entering into Ihram. Then she would bathe while the band was still tied on her head. If she sweated, she would bathe, and the Prophet (peace be upon him) did not prohibit her from doing so.
