Long-term FUE results

[Swooping]

It is true regardless of procedure performed. The theory of donor dominance states that there are hairs genetically resistant to the effects of DHT thus is why we have the term "permanent safe zone". This is a fallacy however for a couple of reasons. Some peope do have hair in the donor zone that is not resistant to DHT and this is what Arfy is referring to as some people age. It is very VERY rare to see a majority of donor hair being DHT susceptible but even on a moderate level it can be a game changer. The other reason it may appear that the density is reduced is an illusion due to senile alopecia where the hairs are miniaturized by not because of DHT. The hair shaft simply narrows but the density remains the same so the finer nature of the hair makes it appear as if there is less. Regardless, they both have a visible detriment for the donor zone.

Joe pretty much every individual will have to deal with a decrease of diameter in hair when one gets older which also (obviously) affects the donor area(1). Senescent alopecia is typically characterized by diffuse hair loss and can hit as early as 40-50 years old. So it can definitely lead to a lower density which is unrelated to the pathology of androgenetic alopecia in the donor area.

All in all the donor hair can indeed deteriorate.
