Head lice

My daughter and I have head lice. I’m pretty sure I got rid of the lice in her hair but I can still feel them in my hair. I have literally no help with my hair. I have long thin fine hair but the lice comb gets stuck because it tangles up really bad when i comb it through so I can’t get it all the way through. I’m going insane. I don’t have the money whatsoever to keep spending on lice treatment because it’s not cheap. My mom has sent me money to pay for it. But she said she won’t come help so I have no help at all. How can I make sure I got rid of it completely?! It probably hasn’t been a good idea but I’ve been treating our hair everyday for the past week. Washing and drying everything I can and spraying lice spray on furniture and mattresses. I haven’t found anything in her hair for a few days now but I need help with my hair… this is my first time dealing with it and I’m so over it already. I want to just scream and cry. I have no clue where it came from

@casey idk if it’s me causing it to get stuck but my hair is so long and it just tangles before I can get it all the way through. My hair is super dry right now. I haven’t been using normal shampoo or conditioner. Same with my daughter but I can run the comb through her hair just fine. It feels more conditioned than mine for some reason.
