School policy on lice?

My daughter got lice at school, on Friday they sent home a note telling me that she had lice. They didn’t even call me to come and get her. She has had lice like 6 times since going to school. I get rid of it, she won’t have it for a while then gets it again. They just did their 1st lice ck on Friday, hence them finding it. I check her hair quite frequently & she didn’t have it 2 weeks ago. I am so mad, shouldn’t they have to send the kid home?? She didn’t this time have any adult lice only nits, that may be why. How can I get them to change their policy? I think they should do weekly checks. My school did that when I was in school, and not very many people get lice.
I know alot about lice, she has had it so many times. They like clean hair,and we wash hers daily. I know anyone can get it, I just feel like they should help get rid of the problem, they don’t notify any parents when a child in the class has it. She get horribly embarrassed and cries each time she gets it. She didn’t come home alone, they sent her on the bus. She also has a small school, and it is a really good school academically. I just hate their lice policy.

I will try the tea tree oil out though, last year we did a vinegar rinse each night, that seemed to work too.
