Removing Cobblestone Scars from Plugs?

i had a hair transplant in 1987. I only went for one session. Now, I have plugs near the temples on both sides of my head. I have shaved down the plugs but there is the “cobblestone” scars
left. Is there anything that can be done to remove these scars. I don’t want to shave my head completely, just get rid of the “cobblestone” scars. Thanks

These cobblestone scars can be excised one-by-one. With a well done procedure, the scar from an excision will not be as bad as what was originally there.
