Got lice from work 😐

I am a home health nurse so I am exposed to different environments all the time. I tried the nix otc treatment but I read some lice are becoming resistant to products like these so I don’t want to take the risk and settling with that. I called a lice doctor to set up an appointment to come to my home and removing them with all natural products, I just want to know its worth it because it’s not cheap😐 Greatly appreciate any experiences you guys may have. Thank you!
