Query: Did not work at all.

For our third bout with lice in three months, I purchased this product from Amazon in the hopes it would save us time and energy in combing out all the nits. Unfortunately, despite our diligent use of the product, it didn't loosen the nit glue AT ALL. My daughter has fine straight hair, relatively easy to get nits out of, and I didn't notice any difference in the ease of removing nits after using this product. I also found numerous living lice on her head after we washed it out.
