Initial growth after hair transplant- Do all hairs need to grow a little?

[Bald_Canuck]

in regards to graft survivability and hair growth do ALL transplanted hairs need to visually grow slightly before the shed ( if you do shed ) in order to confirm that they are healthy and have found a blood supply/not transected? or can grafts be transplanted and shed at the same length they where extracted at without any signs of growth?

It doesn’t matter. By month 3 all of them fall out.

 

But yes those hairs that do stay and grow a little it’s obvious they made it.

Yes, I understand that.

 

But do all hairs have to grow initially to show they made it. Or like I mentioned can hairs be transplanted and remain the same length without growth, shed, and survive to come back months later?
