Lice infestations are at epidemic proportions and lice have become resistant to pesticide lice shampoos, as reported in a recent Harvard University study. There are more studies that were conducted stating lice were showing a resistance to pesticides as far back as 1983. Before Nature's Best, all the lice shampoos on the market consisted of only one type of product, pediculicides. There were no alternative choices. If your child contracted lice, no matter what brand of lice shampoo you chose, it more than likely contained pyrethrum, permethrin or the now banned by the UN Lindane, all extremely harmful and toxic pesticides. Consumers are finding it necessary to use pediculicides more often than the recommended dosage, which can be extremely dangerous. A typical 2 ounce bottle of an over the counter lice killing pediculicides shampoo contains a higher concentrate of pesticides than a jumbo spray can of household insect killer. Nature's Best, leaders in the research and development of safe formulas, developed our Lice Away Enzyme Products to give consumers a safe alternative.
