Q 1: There is a woman who experiences pain in the head whenever she washes her hair during Janabah Ghusl (full ritual bath to cleanse of sexual discharge), especially that her hair is very thick.
Is her Ghusl complete if it is done with the exception of the head?
A Junub (person in a state of post-sexual ritual impurity) should wash their whole body to achieve Taharah (ritual purity) from Janabah (major ritual impurity related to sexual discharge). If there is part of the body that is harmed by water, and it is covered by a bandage or so, they can wipe over the bandage. If it is not covered by a bandage, they should perform Tayammum (dry ablution with clean earth) for it.
