Taking neck hair, which is often finer than scalp hair, has problems with it. These problems include:
(1) more prominent scarring occurs in the neck and the neck area is very visible so such scars will be detectable as punctate scars
(2) neck hair is often not permanent hair as scalp hair is, so if one transplants the frontal hairline with these finer hairs, they may disappear with age.
This is a warning to those who see this press release. They must know the risks associated with a neck hair donor area.
