Ihraam

Q: I am traveling to Musjid Al Aqsa and intend to make niyyat and wear ihraam from there to perform my umrah. 

Can I vape while in Ihraam due to the lengthy time as it will be about 20 hours?

Q: I am a woman who has always performed Umrah wearing a hat and covering my face. Recently, when I was about to perform Umrah, my sister-in-law insisted that I could wear my niqab directly without the hat, as I would only be wearing it for a few hours, and damm would not be waajib upon me. However, I disagreed with her because I felt that this would compromise the essence of Umrah. 

I believe wearing the niqaab in such a manner involves intentional contact of cloth with the face, which contradicts the principles of ihraam. The allowance for unintentional contact exists, but wearing the niqaab directly seems to me like a deliberate act, done only to avoid the inconvenience of using a hat. 

Please clarify my doubt: 

1. Can I intentionally wear the niqaab directly without a hat and perform Umrah? 

2. Can I wear gloves during Umrah as many Saudi women point out during Umrah that it's haraam?

Q: Can a hernia patient wear underwear in ihraam?

Q: My father has a small problem with old age and urine drops. He says straight after he goes to the toilet, about 5 or 10 mins after, he has some trouble with few drops. Then it subsides. 

He usually uses tissue with his underwear for a few minutes after going to the bathroom in case any drops come out and then discards it a short while later. 

He's concerned with ihraam and how would he manage. 

What would be suggested? Is there an option to wear underwear and pay damm? Or is there any alternative.

Q: Is it permissible to scent the ihraam towel before entering into the state of ihraam?

Q: If going for umrah with Ethiopian airlines, when one stops at the Ethiopian airport for transit, can one put on ihraam at the airport but only make niyyat of going into ihraam in the plane when the plane is flying close to Jeddah?

Q: A woman washes some clothes and sets out for umrah and enters into ihram. 

Whilst in the state of ihram, will it be permitted for her to wear these newly washed clothes despite some of the fragrance of the washing detergent remaining in them?

Q: My hair is very thin, especially my beard hair. If I make wudhu and do khilaal, then sometimes, few hairs fall off. 

I'm planning to do umrah inshallah. My question is that if I am in the state of ihraam and hair falls off accidentally while making wudhu etc., not on purpose, then will there be damm or anything necessary?

Q: Years ago I made umrah and then I made an overnight visit to Taif. Was I suppose to perform another umrah on my return to Makkah?

Q: Can one perform Umrah with one of those umbrellas that has an elasticated band and you can wear it on your head leaving your hands free... especially when the temperature exceeds 30+ degrees?
