head lice
"After speaking with the doctor, they advised that I could comb out the nits after using this product, but that both had used it with success and no comb.
Instructions for the product say leave in for at least 10 minutes. I stuck my seven-year-old naked in the bathroom and let him play in an empty bathtub with some plastic toys after completely covering his head in the product. After the hour, I washed his head thoroughly with Ivory bar soap.

I then proceeded to vacuum all of the floors, strip and wash all of the bedding in the entire house, all of the towels, and all of the clothes that weren't in the dresser. Spray the couches liberally with Lysol (enough that they are damp). Every single stuffed animal also went through​.

No more lice!"
