Some FUE transplanted hair have not shed after three months and remain the same size. (photo)

If you are worried about post operative issues, go back to see your doctor for an exam.  In general transplanted hairs will shed over time as you wash your hair.

If they aren't growing and aren't falling out, it likely just means for whatever reason you'll have to wait until those particular grafts start to grow their own hair in the next several months. Those hairs should push out the dormant transplant hairs if they still haven't fallen out by then. If that doesn't start happening when the shedded grafts start sprouting, talk to your doctor.

when you pull them out with your fingers or tweezers, they will come out easily as a piece of dried grass/branch that means they are not living hair.
