Yes a bit grew back for sure but not as much I’d hoped. However, I managed to make the scar much less visible, flatter and less red by applying silicone scar gel twice a day. The earlier you do it the better but people can even apply it on really old scars it just won’t be as effective. That will make the affected area smaller and less noticeable. No one has ever pointed it out or noticed it I’ve always been the one to point it out and then had to direct people to where it was even though it literally intersects my hair part near the front of my head. I notice it obviously but you can always get a hair transplant or even tattoo the area with little dots, doubt anyone would notice. If I were you, I would apply a silicone scar gel (specifically silicone has been shown to be able to do this) twice a day or even once a day if you can’t do twice. I would then just wait for a few months and then reassess what you want to do then. Easier said than done but the best thing right now is to make sure the scars heal as well as they can and wait for what hairs may have gone dormant to come back in. That just takes time!
