I am so sick of my daughter getting lice. There's been an "infestiation" in her school since last year, she got it twice and we managed to get rid of it. Then we went all winter, spring, and summer without her getting it and two weeks after school started back this year she and almost every other girl in her class had it again. Even with spraying tea tree oil on her head, using tea tree shampoo, and coconut conditioner. She hasn't had bugs but the nits are insane. I think the oil kills the nits but they're still stuck to her. Her hair is so thick its so hard to comb but I manage to do it but they don't come out. I lathered her head in mayonase today and covered it with a shower cap, let it sit for 3 hours, rinsed and combed with a metal comb. STILL there. If you pull aside half of her hair it looks like she has snowflakes or something. It's awful. Still not bugs, I've checked and checked, but I need these nits gone, they keep getting worse. I've also washed and cleaned all the linens, animals, and hats. I don't know what else to do. I know there are ways to get rid of the bugs like prescription medicine, and listernine has worked wonders in the past, but I need ways to get rid of these nits.
