Potential scarring, pitting and lumps in the recipient, potential of infection or necrosis, poor yield will be see through and clearly like a transplant, density issues could mean it won't match the hair behind it, very often poor doctors angle the grafts poorly which looks unnatural, they could design the shape of the hairline in a way that is unnatural or silly, you could get shock loss in the donor and have patches with no hair in the donor area that don't grow back, you could get shock loss in the recipient which would cause hair close to the recipient behind the transplants to become lost permanently, you could be left with a permanent pink area in the recipient which if nothing grows in it will look ridiculous, your donor is also finite and wasted grafts mean you will have nowhere to draw grafts for future procedures.
Yeah, not exactly worth f*****g up your life over in your position, which isn't all that bad yet. Find a capable doctor if you need this, not a random Indian sh*t head.
