Transplanting Hair Into a Cleft Lip Scar

Hi I have a keloid scar from a failed surgery in the past. My keloid scar is located from my left nostril to the bottom of my upper lip. (cleft lip) Is it possible to transplant hairs on the keloid scar? has such a procedure ever been done before? I know you transplant hairs on lips not sure about on top of a keloid scar.

If this is a cleft lip scar, it is rarely a keloid. These scars make good transplant recipient sites and many people have grown transplanted mustaches to cover the cleft lip scar.
