Transplanting on half-bald parts

[Krembo]

Good people hello

Is it possible (and is it common) to also implant some hair all over the scalp top, where there is still hair but not like it used to be, instead of implanting it just at the bald parts? (Assuming that i have enough donate hair for that ofcourse)

So im asking abot the half-bald parts,

But also about the normal parts that are just not as full as they used to be.

Thousand thanks!!
