PICO or Q-Switched laser? I had a small black tattoo lasered a few years ago. It didn't respond well at all. I did six sessions over the course of a year with a Q-Switched laser which was the only type available in my area. After six sessions, it was finally light enough for up for a coverup. Good luck! I know the neck must suck...good luck!
What @oboogie said, times 10!!! That poor tat is drowning.
You won't know until it's healed, four to six weeks out.
On another topic, why would you go to someone that isn't that experienced?
