Once follicles have been removed by Follicular Unit Extraction (FUE) they are gone from that area and do not regrow.
Donor hairs do not grow back. This is true for any hair transplant surgery. You are transferring hairs from one location (donor area) to another area (face/ beard area).
Generally speaking, the extracted hair follicles do not grow back. However, if you have good density in the donor region you definitely should not notice any type of thinning provided the FUE procedure is performed properly.
Once follicular units are extracted from the donor sites, the hair will not grow back. However, usually the extractions are taken with a bit of space In between them, and that space where the extractions were not taken will grow back., therefore after FUE there is coverage in the donor area but generally it is thinner.
With a properly done FUE procedure, especially if done with the ARTAS robot, there will be no signs that hair was taken from the donor site.
Hair is harvested carefully with adequate spacing between harvest sites. If this is done, there will be no sign that hair was taken from the donor site. As the grafts have been taken out individually, there will be no scar.

If you are a non balding man,you should have no problem with donor coverage for the 2000-3000 grafts it takes for a beard transplant. The hairs will not grow back but there should be plenty of hair to cover the back and sides of your head. If you have a significant balding problem you will have to decide if you want your limited donor hair supply used for a beard or for scalp hair.
No, the donor site hair does not grow back. Whatever is removed is gone forever.
We have between 0 and 11,000 permanent donor hairs to remove from the back of the scalp. Your surgeon can guide you with a rough estimate of where in this spectrum you might be.
The hair which is removed from the donor site will not grow back. Those follicles have been harvested and shifted to the new location (in your case the beard). Harvesting should be limited to 10-15% from the donor site depending on your donor site density (ie the amount of hair you have on the back of your head). It the harvest percent is kept between 10-15% it would be nearly impossible to tell anything was removed. Good luck and be well, Dr. M
Any hair that is transplanted from a donor area is moved elsewhere so it never grows back. That is the concept of hair transplantation in general, moving hair from a permanent area to an area that is not permanent (the balding area).
