Unfortunately, you are not a good hair transplant candidate. You have a large crown dipping downward and retrograde alopecia dipping upward. This leaves you with a very fine line of suitable donor hair. I don't know whether you are on medication, but my advice is to get on medication for at least a year to see if some of the miniaturized hair in the crown can recover. If you're happy shaving your head, you should continue. It will be a LONG and EXPENSIVE road if you decide to get surgery and remember, there are no guarantees.
