Save yourself $$$ and don't even bother with this product.
After a pediatrician confirmed that our 7 year old has lice and that our younger one was clear, we purchased this kit from the store to use on our younger daughter. It failed miserably!  Within a few days, the nasty pests had ingested her head too. Also, the detangling spray bottle was clogged and stopped working after just one use. Waste of money.
