Woman with extremely short hair cutting her hair to come out of ihraam

Q: A woman who has extremely short, curly hair (like is commonly found among the local communities in South Africa) goes to perform umrah. 

How does such a woman remove her hair to come out of ihraam, as she will not be able to gather her hair around a fingertip and cut a little more - her hair is too short for that. What does she do? Please advise.

Moving into a house with some stuff of the old owner

Q: I have moved into a new home. The previous owner was not Muslim. He had left some baking trays that fit into the oven that he left here which I presume he was not using. I am not sure if he would have cooked any haraam food with the trays. I wanted to throw his trays away but now some of my baking trays were placed in the same draw and they got mixed up so I don't know which are mine and which are his. Is it fine if I end up using the dishes that he used to cook with as long as its washed with sunlight and water?
