FUE (follicular unit extraction) treatment for hair growth

Q: There are a few individuals that have done FUE (follicular unit extraction). The procedure involves taking a persons own hair and transplanting it to areas of the scalp where hair has thinned.

My understanding is few weeks after the procedure there is also natural growth in these areas and the hair can be cut and will regrow naturally.

Is this procedure using your own hair permissible?

Travelling while in iddat

Q: I’m on iddah at present and have been keeping to the confinement of my home as per the rules of Islam. However, my daughter has been experiencing emotional and psychological distress to my divorce as we had to pack up and leave our home in a few days and start a fresh. She is seeing a therapist at present. 

My brother is going away for the weekend and suggested that I join him with my daughter going to the destination and staying in the room whilst he does activity with her. I unfortunately have to drive because he is taking his family with him and there is no space in the car. Is this allowed considering the circumstances. It’s been six weeks since my iddah and I don’t don’t want to break the rules.
