Hey there, I actually got a transplant about 13 years ago. It didn't turn out too well and I still have the scar. I can get the scar fixed through SMP if I decide to go that route, but transplants are just too expensive and simply put, I regret doing it. All the transplanted hair is no longer there for me.
As for the partial pieces, I don't want to look drastically different than how I look now (a receding hairline all of a sudden), but I just want to display that my hair is thinning out more and more.
