Hi Xia,
I think only your surgeon can tell you this for sure. From what I am gathering, a large number of women (including me) have the hairline lowering procedure and then finish it off with a number of hair transplant/micro grafts. This is especially true for those of us having brow work done at the same time as it can be completed in the same procedure. However, if you don't need brow work done, and your hairline isn't that receded (well, even if it is, but you would need to transplant more hair), you can definitely do just the transplant surgery by itself. But do a board search and check with some of the other ladies who have had this done. I do believe that for some people use of a hair growth supplement (Minoxidil, I believe) is in order. It depends on where exactly the areas of loss are.
I hope this helps.
