Tricho Donor Closure Results

[ChickenMan23]

This may sound like a stupid question but every time I see a same day post op picture posted of a tricho donor closure there seems to be a very wide area where there is no hair. Typically you will see a pattern where the hair from the top of the ears to the bottom of the ears is completely gone with a small strip in the middle of buzzed down/shaved hairs. Why is this. Is the buzzed/shaved hair the hair actually growing through the scar (seems too early). Can someone explain why this is and where the actual scar is.
