Study: Most head lice resistant to OTC allopathic remedies

As many as 88% of lice may carry the gene mutation. 

"This gives most of today's head lice an ability to withstand exposure to the main — and previously effective — ingredients found in most nonprescription head lice drugs: 'pyrethroid' compounds, such as permethrin," the report stated.
