Grafts Growing in Scarred Tissue

Does a graft always have the potential of growing? Even in an area of scarred tissue? Or where a hair has been extracted?

If the scar tissue is healthy scar, it will support follicular units. Healthy scar actually bleeds when cut. Scars often have a rich vascular network, but some skin grafts (split thickness grafts) and burn scars may not have enough vascular support for a hair transplant. A healthy graft will grow anywhere it is placed when the blood supply is adequate. For example, a follicular unit placed on the end of the nose will grow to pony tail length.
