Eyebrow Transplantation - What Happens when Transplanted Follicles Turn Gray?

Transplanted hair retains its texture, color, growth speed, and length. Thus, hair taken from the body and transplanted to the head (in body hair transplant) or, in this case, hair taken from the head and transplanted to the eyebrows will retain these innate characteristics. If your scalp hair is meant to turn gray, there is no way to prevent this from happening after its been transplanted to the eyebrows.

With any hair transplant procedure, including eyebrows, the transplanted hairs retain the characteristics from the donor area where they originated. If a particular hair is destined to turn gray, it will still turn gray after being transplanted to the eyebrows. While there is nothing that can be done to prevent transplanted hair from turning gray, the hair can still be easily colored like any other hair.
All the best,

Transplanted hair may turn gray as you age like any other hair.  Transplanted hair is not immune from turning gray.
