hair still there

About a week ago, I got my first treatment on my bikini area. After reading about all the potential problems, I decided to go with a technician recommended by my dermatologist. The Lightsheer Diode was used at a setting of 22. I have medium skin and dark hair. I thought this was too low a setting, but she said she didn’t want me to burn. A week a half later, none of the hair has even fallen out yet. I can pull it out with my hands and most hairs come out pretty easily but some resist even if I use tweezers. Is this normal? I have already paid for 3 sessions and this is the first. I am angry that I seem to have wasted this session.

Thanks in advance for any responses!

I guess I should have read the topics more closely. It seems my question was answered before. Thanks for reading!
