How much density should there be left in the donor per cm2?

[Cory]

Hello everyone,

I bet this also depends on hair thickness, but I was wondering how many hairs would be the bare minimum to be left in the donor per cm2, after your final procedure.

Is this something that doctors have a rule for?

They don’t measure it really, it depends on what the patient is comfortable with, some patients don’t want any visible thinning in the donor. Others don’t mind a uniform thinning that makes their scalp look homogeneous.

That makes sense.

I figure hairstyle is also a factor in this, as longer hair can give more an illusion of density of the donor than a really short trimmed one. But then still maybe a really short donor can more easily be filled with SMP.
