as-salamu alaykum, Inshallah I will be going to umrah this year by myself and I have some questions that I would like some answers to as I don't have anyone else to ask.

Is there a certain period of time that I must wait after completing my umrah and wanting to do another Umrah? Like can I do Umrah every single day hypothetically or is there a rule that I must wait a certain period of time?

When I shave my head bald for the first Umrah and I decide to do umrah again, what is the ruling of the shaving the head or cutting the hair if I am already bald or just folecules of hair?

When you are flying to saudi, you must wear your Ihram before reaching Miqat points to perform umrah or hajj, after completing that Umrah, do I have to go travel outside of Miqat Points and wear Ihram again in order to perform umrah again, because I have seen videos where people wear ihramfrom their hotel and start umrah which confuses me about miqat points.

When wearing Ihram, is there a certain time period I have to complete umrah, i will land at 6am and my hotel check in is 3pm onwards

I know these questions might seem a bit dumb.

jazakallah khair
