oh...
well, it seems like either the 50cm2 density that the doctor inserted did not totally survive,
the grafts inserted into the existing hair damaged the existing hair follicles
and/or set them into their non-growth period,
or
50 grafts/cm2 density was not enough given your hair characteristics to not give the see through scalp look
don't fret
this is fixable
consult with some docs
realize sometimes this happens and may not be due to the doctor you have chosen
