hi not easy is it...heres the thing, they lay eggs on the bed sheets, pillow cases and towels anything touches your child's head, you have to wash and keep washing, they also do not like being disturbed, so you have to comb with a metal tooth and comb.as much as is possible ..If you just wash with one lice shampoo thats not enough, they are resillient little critters...so get after them ,shorter hair would help if your daughter would like a hair cut. if her hair is long.Get her combing herself , and you and her Dad keep at it ...,
