There is really no need to keep her home. Treat her with tea tree oil or some other OTC lice treatment (don't use RID, I think lice have built up an immunity to it!). Then, put her hair in a braid and send her to school. Lice cannot jump. The spread from the lice crawling from one head to another. They have lice deterrent products you can put in her hair or you can put other products - hairspray, mouse, etc. Lice don't like products in hair because they cannot attach the nits (eggs) to the hair shaft if it has product on it. Use the lice spray and spray her mattress and pillow, wash all bedding and dry at the hottest setting. Spray any cloth chairs, couch, etc., even car seats. Put all stuffed animals and other cloth things that can't be washed in a garbage bag for a couple of weeks. Goggle the life cycle of lice - if you do a follow-up treatment in 10 days as recommended, you should be okay. Lice eggs hatch 7 days after laying and lice cannot lay eggs for 5 days after hatching so if you follow-up in 7 days, you get all the baby lice that come from the eggs that you missed when you treated her hair the first time, and they won't have time to lay more eggs so that pretty much does it. It's not that hard if you just take the time to do it right.
