Everything is possible . You can imagine combos : Fue+powder, Fue+hair system, Fue+smp…The goal is to forget your hairloss. But You don’t want to add other “problems” if you are not confortable with them(powder, hair sytem etc). The point of a hair transplant for a high norwood is to have a solid 1st third and middle scalp and “ok” crown. But of course it “easier”(you see what I mean) for a guy of 30+ yo to pull it off . If you have a solid hairline / first third you can let it grow and you look definitely better and you will obviously feel more confident even if there is a lack of density behind. Of course I talk of high norwood who go for hair transplant, they have other wishes than guys who have temples recessions.
Some also imagine to go for a mega hair transplant (like 7/8kgrafts)and have smp in their donor area to hide the white dots and keep the donor area shave. I don't think it has been realised yet. costly too..
I mean there is a solution for everybody but it 's not that easy
