Maximum Number of FUE Grafts

What is roughly the maximum number of grafts one could expect to get with FUE and still be able to shave the head completely afterwards without noticing any scarring?

The answer depends upon the size of the punch and the way you heal. The smaller the punch, the smaller the scar. On some people, I could not find any scars from FUE (Follicular Unit Extraction), but did notice the missing follicular units. I always wonder why (assuming you are not an actor) you would want to have a hair transplant if your styling choice is to shave your head.
