Hair transplant questions..please..

[Fairly]

Hello,
Sorry if this is the same old newbie stuff.
I have come to realise a future without hair isn't for me.
I am just wondering if anyone could help me with some questions.
Would I have to take finasteride after a procedure? I'd rather not.
Could I continue to use minoxidil?
Once you have had a transplant, is a shaved head out of the question due to scarring?
Is there a limit on the amount of procedures you can have?
If you have several hair transplants what sort of time limit is needed in between?

Many thanks for any help,

Paul, UK
