Can I get SMP over transplanted hair area?

I am a young woman and had FUT hair transplant for hairline lowering 1,5 years ago. The result is nearly perfect, but the only thing that bothers me is that in certain angles my scalp shines through the transplant area, because the hair is more sparse than my natural hair, my hair is dark and my skin super white. This does not bother me enough to go through another round of FUT, but I was wondering if I can have SMP on the hairline are where the grafts are?
