A friend of mine had a similar experience with him except from fue
He had fue where a he uses some sort of drill/vacuum device to extract the grafts.
I believe its called neograft.
He has horrible growth at 11 or so .
He said the doctor said some guys just dont grow.
Sounds like a shady guy to me.
Your going to probably have to go the fue route for the higher scars.
Good luck and Im sorry this has happened
