Getting only one transplant to cover whole scalp?

[aman123]

I'm new to this forum completely, and I'm 22 but have considerable hair loss all over my scalp (crown, hairlines, etc.). It's been going on since I was 15, but basically, I kept losing hair everywhere and now you can see patches of my scalp pretty much all over the top. It's really embarrassing.

There is still hair there, and chances are, all of that hair that is there right now will fall off. At the same time, my 33 year old brother has hair kind of like mine (where the scalp has thinned out a tad, but hair is still there enough - his began early also), so mine could potentially stay the way it is now.

I realize I'm young, but I'm getting a consult soon. I can't stand losing my hair; quite literally, its ruining my self-confidence and I have to apply concealer all over it every morning to hide it.

Can't I just get one big transplant in which a whole bunch of donor hair from the sides/back are put all over the entire scalp, even in areas where hair growth is still present? Basically, the idea is to get the scalp completely covered with transplanted grafts so that even when the old, native hair falls out in the next few years, there will still be enough transplanted hair to where it still looks full/thick (aka future hair loss won't be noticeable)?

I'm allergic to propecia and with Rogaine, my ears swelled hot red and became all peely and itchy, so I'm not taking either of those
