when do grafts stop shedding?

[HarryHonolulu]

hey all

I am 6 months post op and growing well

however when I shampoo in the morning I notice a couple fine hairs in the palms of my hands.

wondering if this is "new" hair that's still shedding, or whether it is my "old" hair that is still falling.

which leads me to ask, does the transplanted hair shed this far into the process? 

I am on Propecia, Rogaine if that matters.
