Lice becoming resistant to treatments, study says

Results from a new study may leave you scratching your head.

Head lice populations in at least 25 states have become immune to most over the counter treatments.

Researchers at Southern Illinois University gathered lice samples from 30 states. Nearly all of the populations they tested showed high levels of gene mutations, making them more resistant to the active ingredient in lice shampoos.

Samples from 25 states contained all three mutations and four states had lice with at least one mutation.

The resistant lice can be treated with different chemicals, but some are only available by prescription.

Researchers are finding that head lice that are becoming resistant to OTC treatments. Red states: 100 percent of the tested lice were resistant. Orange states: 50 to 90 percent of lice were resistant. Yellow states: 1 percent to 49 percent were resistant. Blue states: Data hasn't been analyzed yet. White states haven't been tested.
