Do Chemical Lice Shampoos Work?

Updated on May 14, 2017

chemicals do not work on lice

Unfortunately, they often do not. "The days of being able to wash with some pesticide-infused shampoo are gone.", states Sara Zukoff, assistant professor of entomology at Kansas State University in an article in the Wichita Eagle written by Gabrielle Dunn. Professor Zukoff lays the blame for this on the growing resistance of lice to the chemical treatments. She likens this trend to that of growing resistance to antibiotics due to overuse. According to the article, Zukoff reports that "a small segment of insects carry resistance to the pesticides. When those pesticides are used over and over, the pesticides kill the bugs not resistant and the ones with resistance slowly become more common." We at LiceDoctors endorse this assertion. We have been out in the field, treating families in their homes for over 20 years. We have first-hand experience seeing live lice crawling on the head after lice pesticides were used. Parents are often perplexed and horrified to discover that the chemicals did not kill the bugs. LiceDoctors uses a chemical-free protocol that gets rid of of all lice....even mutated ones that are resistant to chemicals A recent study showed that lice across the country are now resistant to chemical lice products. The study at Southern Illinois University found mutated head lice in 25 of 30 states studied, including Missouri. In a report by the American Chemical Society in August, 2015, the author of the studied reported, “We are the first group to collect lice samples from a large number of populations across the U.S.,” says Kyong Yoon, Ph.D. “What we found was that 104 out of the 109 lice populations we tested had high levels of gene mutations, which have been linked to resistance to pyrethroids.” This growing resistance to the chemicals is one of the major reasons for the increase in the incidence of head lice. People use the chemicals, then assuming that their kids are lice-free, they send them into the world still contagious. Ultimately, these unknowingly infested kids pass along lice to others. At LiceDoctors, your technician apply product to suffocate the bugs and loosen their eggs (nits). She will  comb through the hair with a professional grade comb handpick the nits from the hair. This task is best done by a trained professional who can identify and find the nits that camouflage in the hair.
