How can i prevent head lice, and how do you get rid of them?

Hairspray helps.: Head lice do not like hairspray so this can be a great preventive. To get rid of lice, you can use various topicals but some forms are now resistant. Study last year showed oral Ivermectin can be used for head lice--one time treatment and works like a charm. Of course, make sure the children are not sharing hats, headbands, barrettes, etc.
