The perfume that is forbidden to the pilgrim in ihram includes scented antiperspirant. But if a person did that out of forgetfulness or ignorance, he does not have to do anything.

It is permissible to use a truss before Ihram during Hajj and Umrah even if it is stitched.

If the pilgrim does any of the restrictions of Ihram deliberately with no excuse, he has sinned and the violation is of three types: 1. That for which there is no Fidyah, which is entering into a marriage contract. 2. That for which the Fidyah is to sacrifice a camel, which is having intercourse before the first stage of exiting Ihram. 3. That for which the Fidyah is to fast for three days, which may be done consecutively or separately, as he chooses; or to sacrifice a sheep of a type that is acceptable for the `Eid sacrifice, or one-seventh of a camel or of a cow instead, and to distribute its meat among the poor and not eat any of it himself; or to feed six poor persons, giving each one half a Sa` of staple food. He is given the choice between these three options if he removes any hair or nails, puts on perfume, touches a woman with desire (but without having intercourse), if a woman puts on gloves or a face-veil, or if a male puts on form-fitting clothes or covers his head.

In cases of necessity, there is nothing wrong with the pilgrim in ihram wearing a mask such as if he has an allergy in his nose and he needs to wear a mask.
