The process of balancing a hairline, ie: placing grafts in a way that the hairline is more even is not difficult.  The real challenge for this kind of procedure is 1. Getting the density on the transplanted side high enough to blend in with the side you are trying to match (often takes more grafts than you might think), and 2. making sure you are treating what ever caused the hair loss to begin with.  Even in the absence of family history, it is possible that you can have additional loss.  Now imagine you have placed grafts into one corner and then you lose the remainder of the front 1/3.  That can look unsettling.  FUE is an excellent choice but no surgical procedure is 100 percent scar-less. Shaving with a razor may result in seeing some dot like scars or slight changes in skin color. This is more prominent in the donor area.  Typically a 5 o'clock shadow length will sufficiently cover FUE scars.  At the end of the day most hair loss issues require a comprehensive approach to the problem to truly solve it.

What you are describing is generally post op shedding.  Any time you have a procedure to a body part that contains hair, this is a possibility.  It is just more disconcerting when you come in for more hair and temporarily get less...  The good news is this is temporary, the bad news is its annoying and will take 4-7 months to come back in.  Transplanted grafts will also be falling out after 3 weeks or so, so you are on the correct pathway.  Hang in there.  Hair transplant results are like running a marathon as opposed to a sprint.

Generally, unless you got bleeding, there is no harm done.  A stretching sensation can be caused by a number of factors.  Grafts dislodged immediately after surgery almost always results in bleeding however.  Its therefore unlikely that you caused any significant issues.

The 2 main issues that early are graft displacement, and infection risk.  At 2-3 days you still have a healing wound essentially.  Dusty and or dirty environments are not necessarily an ideal setting under that circumstance.  Additionally, grafts can be dislodged from trauma, or from any head gear that compresses, or drys and attaches to grafts.  Its doable, but you really need to be careful.  I would suggest a lose fitting baseball cap that doesn't press on the grafts and keeps the head as clean as possible. I would also shower, gently washing the head when you get home.  By day 5 - 7 you will have much less of this concern as the grafts and donor areas are fairly well healed by then. 

From a graft growth standpoint it will get a little thicker.  At your age, however, the probability that you will need a subsequent surgery is very high.  Medication, laser therapy, Rogaine, and PRP my help prevent that, but I would plan on needing more as 2300 grafts is not a full head of hair.  The three main reasons that patients do second surgeries are 1. They just want to add density.  2.  They want to work on a new area.  3. They lose more hair with time.
