Earth Day Alert from Lice Clinics of America®: Pesticide-Based Head Lice Products

Every year on Earth Day the world focuses on environmental protection. Lice Clinics of America uses the day to remind the public that all of its products and services are 100 percent pesticide-free. The company’s signature clinical treatment using the FDA-cleared AirAllé® medical device is proven to kill live lice and more than 99 percent of eggs (nits) using nothing more than heated air to dehydrate the bugs and eggs. Treatments take about an hour and are guaranteed to be effective.

Many people don’t realize that traditional lice products rely on pesticides to kill head lice. Parents routinely wash children’s hair in pesticides without knowing it.

Pyrethroids, the class of pesticides used in popular over-the-counter head lice products, are neurotoxins that kill lice by paralyzing the bugs’ central nervous system. Pyrethroids are also common in home and garden pesticide products such as bug sprays and fogs. A study by Cincinnati Children’s Hospital found an association between pyrethroid exposure and ADHD, particularly in terms of hyperactivity and impulsivity. A separate study presented at the 2017 Endocrine Society conference linked pyrethroids to early puberty in boys.

What might be even more alarming is that the products are no longer effective. Pyrethroids have been overused for so long that head lice are now resistant to them.

Immune lice have been dubbed “super lice” in the media, and now most lice fall into this category. Research published in the Journal of Medical Entomology found that 98 percent of head lice in the United States and many other countries are now immune to pyrethroids. The AirAllé treatment is effective against super lice because it doesn’t rely on pesticides at all.

Lice Clinics of America wants the public to know that there is no reason to use harmful and less effective pesticides on their children when there are faster, safer, more effective alternatives available.

Scientists have also found high levels of pyrethroids in U.S. watersheds. The U.S. Geological survey said that it has “detected pyrethroid insecticides in stream waters in urban and agricultural areas,” a report said. “Highly toxic to fish and invertebrates, the occurrence of pyrethroids in aquatic environments has become an ecological health concern.”

Lice Clinics of America also offers a complete line of non-toxic home lice treatment products, including preventive sprays, shampoos, and conditioners that can keep children from getting head lice in the first place. The company launched an at-home version of the AirAllé device in 2018. Called OneCureTM, the device comes with the same guarantee as the AirAllé device. All products are pesticide-free and also guaranteed to be effective when used as directed.

With 330 clinics in 35 countries, Lice Clinics of America is the world’s largest network of professional lice treatment centers. AirAllé has treated more than 800,000 cases of head lice around the world with a success rate better than 99 percent.
