Hair transplant for Norwood 2. What to expect when hair loss progresses?

If you look like a Norwood 2 now but you think there is a good chance of progressing to a Norwood 6 then go see a doctor.  You need a good "Master Plan" and plan your hair restoration process carefully.

I know what you're asking. The short answer is yes. But it doesn't matter. Patchy irregular area of hair are normal even for people who've never had a hair transplant. That's why very uniform HT results are still obvious to the casual viewer. The good HT surgeon breaks things up to fool the eye. What we do in a patient with progressive hair loss is start at the hairline and move backward. The hairline is the foundation of the house, so to speak. So as you age and lose more hair, move backward. You won't really notice the thinning area between transplants because the transplants from the first procedure will cover it for the most part until that area is transplanted. You will know when to do the second transplant, don't you worry about that.

It is in men such as yourself that medical therapy is really important.  Using medications like finesteride will slow your hair loss progression.  If you add to your hairline now and then allow nature to take its course, you'll look really odd when you continue to recede behind your new hairline.  An option at this point would be to go ahead and graft your hairline AND your forelock/midscalp -- but I'd really recommend saving that for another day.  You've already accepted the other big factor which is knowing that you will need to do it again someday.  When is tough because it depends on how rapidly you progress (and how well finesteride can slow the progression).  Do the second grafting before it look weird!  I would really look in to FUE as opposed to strip grafting so that you don't have to contend with the scar in the future.  ARTAS is great -- check it out.  Good luck!
