Embarrassing

Super embarrassing but I somehow came in contact with lice and I did the nix treatment on Friday and have been religiously combing my hair,using oils, cleaned laundry. Today I had my head checked and no visible lice but had a bunch of dead nits and unfortunately some live nits 😭😭😭😭😭😭😭 WHAT DOES THAT mean? Do I have to do another round of nix? And can there be live nits and no lice? I’m just so overwhelmed with this I’m totally embarrassed and don’t know what to do. Any advice or any products to buy?
