Shock Loss for Previously Transplanted Hairs?

Are previously transplanted hairs at a big risk to shock loss following a second or third transplant?

Generally, transplanted hair is “permanent” and are not at risk of shock loss. Some hair loss may occur immediately after a hair transplant, but it should not be permanent if it is transplanted hair that has fallen out. I have seen shock loss in previously transplanted hair in less than a half dozen men and the hair came back as full as it was in all of them.
