HT cobblestone

[aim4hair]

Can someone explain to me what exactly is cobblestone ? is it the big circle around the grafts that you can see alot on old transplant? or is it like some bumps on the scalp that make the recipient surface not really even in some places even though the hair grafts has no circles around them and look very normal?
Can you provide a pic explaining exactly the cobblestone in the recipient area that so many people talk about ?

You are correct... When the graft doesn't sit perfectly flat with the surrounding scalp. A "cobblestone" is raised above (a bump) while "pitting" is below the rest of the scalp (a divot).
