Diameter of Punch?

[Mike2020]

Presumably the smaller the diameter of punch used during FUE, the less visible scarring will be afterwards?

.9mm or less and it varies on the caliber and texture of your hair. Anything over 1mm and your risking noticeable dot scarring.

But scarring isnt the only issue to be worried about. If they extract it improperly you can end up with density bands behind the head. If you get a fade, an outline can appear where extractions were made. Example, in my case a large rectangular compressed extraction pattern appears. So it defeats the purpose of having a very clean fade look.

i heard that punch is individual but as Sean said, no more than 1mm
