Anyone experience crown loss shock where no grafts have been placed. I had 1800 FU on hairline and top, right up to crown area, but not on crown. 4 months later crown started shedding.
I too had 1800 units tranplanted last june. All of the units were used in the frontal area. I too have a feeling that my remaining hair is shedding faster than before.
Shock loss can occur in other areas besides where the transplanted grafts were placed... anywhere there is hair "at risk".
Propecia is a good idea, but don't wait until you start shedding to use it. You should be using it all along for prevention, as soon as you noticed a hair loss problem in the first place.
There is also some information about Minoxidil helping with transplants, preventing shock fallout, helping improve your results in general. The suggestion is to start it several months before your surgery. Of course you would stop using it immediately before your surgery, and for a few weeks while you heal, and then resume using it. Read this, and if interested discuss with your doctor, especially if you have a surgery coming up: http://www.ishrs.org/sciarticle-Minoxidil.html
