Not possible to post a picture without specialist equipment and I'd already pulled them out. There was only ~50 hairs so not able to tell if they grew back or expect to see any big change in density.
Interesting update though - I went in for another round of FUE (3000 grafts) at a different practice. It was such a different experience: the first time they took 7 hrs to do 2200 grafts, this time just ~5 hours to do 3000. They used different equipment so extraction seemed much quicker.
3 months in and the results are much better after this surgery. The hair has grown in much more quickly, thicker and is notably an improvement vs last time. However, I still have a bunch of short spiky hairs. I'm going to give it a couple of months and pluck them too - but they've clearly not grown and not fallen out.
Maybe it's an individual thing. I'll see if I can get a picture, but it probably would need special equipment.
