In an article in the Sydney Morning herald, it reported what many parents (including myself) knew already – over the counter head lice treatments from the chemist don’t work.

The article titled, ‘Head lice becoming resistant to common chemical treatments: study’, reported that head lice have become immune to most of the over-the-counter chemicals used to treat them, according to a new study.

It goes on to say, ‘The study, published recently in the Journal of Medical Entomology, found insecticides such as permethrin – one of the most common treatments for head lice – used to be up to 100 per cent effective in killing the parasites when it was introduced in 1984.’ Read the rest of the article here.
