I think not enough for a FUE with 6K grafts but you should ask for other advices here.
If you have no tendency for bad cicatrisations (hypertrophic or keloids scars) you should consider a FUT and then cover the scar with a SMP. Maybe add some BHT for volume.
You may also consider to cover your entire head with a SMP (start with a tricopigmentation first to know if you'll like it).
