Beard (facial hair) transplant. So I am 5 months post-op and I am unhappy with the density. Options?

Also my beard transplant gave me tiny hole scars. I am little confused to go for another one worrying i could get more scars. My question is what if i go for direct hair implantation. What i am saying is that implanting hairs diectly into the skin without making the recipient site incisions. Last time some of the hairs were inserted without recipient site incisions and those are not much noticeable. What are the cons of direct insertion without recipient site making?Please answer all the cons.
