Can I say something about this?

Hi, just had my 3rd laser treatment done but unfortunately it was with a new nurse who only managed to treat half the hairs in the area. Can I complain about this? The nurse before was so thorough there were only a few hairs left. This one is useless. Your thoughts?

Of course you can, you paid for a full treatment. It’s like going for a hair cut and having them cut half your head and say they’re done.

I would its not cheap after all.

You should wait 3 weeks and then go back in and ask for a touchup on any hair that didn’t shed, especially if there is more than 10% still there.
