A new strain of head lice is plaguing most parts of the country, and it?s becoming resistant to OTC ant-lice shampoos!
According to a report from Today, the strain, discovered by the team of Kyong Yoon, an assistant professor at Southern Illinois University?Edwardsvillle, the lice were to be a super-resistant to pyrethoids, the active ingredient in most anti-lice substances.
In a new study, Yoon and his colleagues decided to find out how widespread these resistant strains were.
“We collected 109 lice populations and 104 had high levels of gene mutations,” Yoon reported at the annual meeting of the American Chemical Society.

Pyrethroids, which are synthetic versions of a chemical found in chrysanthemums, lock onto receptors in insect nervous systems, paralyzing the creepy crawlies and eventually killing them. However, Yoon said that the ice have evolved in such a way that they were able to create a natural resistance to the chemical.
This doesn?t mean pyrethroids no longer work, but you need to alter the dose already, and it will need a higher dose of the substance. Pediatric dermatologist Dr. Robin Gehris said that despite the finding, she still believes in OTC treatments. While they may be somewhat less effective, they still work much of the time, she said, saying that in some cases, the treatments don’t do a thorough job because parents don’t use them as directed.
According to the article, if you’re using an OTC treatment, be sure to apply it a second time five to seven days later. Some therapies don’t kill all the eggs the first time, and those survivors will hatch about a week later. Also, be sure to leave the treatment on long enough.
The better solution? Gehris said, “you want to leave it on overnight with a shower cap. A common reason for failure is that the children don’t like the smell and want to wash it off soon.”
When it comes to home remedies, there are those that suggest slathering on thick substances like mayonnaise or Vaseline as this restricts the lice from breathing and they eventually dies.
“If you want to use mayonnaise as an adjunct, I’m OK with that,” she explained. “Theoretically, it could work if you put it on thickly enough that the lice aren’t able to breathe. But it’s hard to imagine that you could get it on thickly enough to really do the trick,” Gehris said.
Healthy Holistic Living on the other hand suggested the following. Gather the following materials:
- Listerine mouthwash (off-brands work just fine as well)
- White vinegar
- Shower cap or plastic bags from the grocery store
- A couple towels
- Lice comb
To start with, douse the infected?s head with as much Listerine as needed to completely wet their head.
Once their head is completely drenched, gather their hair and put a plastic grocery bag, or shower cap, over it and leave it sit for at least an hour. After enough time has passed, carefully remove the bags. You might be surprised at how many dead head lice are in the bags. Carefully rinse the mouthwash from their hair. Douse their head with the white vinegar. Reapply the bags again. Let it sit for another hour.
After an hour, shampoo as normal. Once done, comb their hair using the lice comb. The vinegar helps to loosen the glue on the eggs, so that way you can easily comb them out.
