Does miniaturization dictate how many grafts you take out

Miniaturization studies help to confirm a person’s expected balding pattern. But let’s say a person is assessed for miniaturization and their hair is miniaturized in a Norwood 3 pattern, how do you know that additional hair beyond the already miniaturized zones won’t also start to miniaturize down the road resulting in an even higher Norwood level?

How I  use the donor area is a balancing act between present balding patterns, evident miniaturization suggesting future balding patterns, and the hidden future potential patterns of balding that are not evident at this time. I always keep reserves from the original donor density calculations I make on every patient.
