Keratin hair straightening treatment in salon kills lice. Expensive but worth it!!! I hate lice!! I have lice again from my daughter's friend who used my brush. If I wasn't nursing I would do keratin but you can't do it if you're pregnant or nursing.

We tried all the over the counter medicines which were not effective. During one infestation I was due to color my hair and we found that hair dye kills them. The good thing about this is you can color your hair the same shade.

This may sound crazy, but I tried NIX and other brands OTC, none were effective on my child until I tried Sargents ScratchX, Suldene flea shampoos. Says right on the bottle for fleas, ticks and lice. I did her head once a week and never had a problem ever again!

I have tried every possible remedy (both natural and chemical), cried many tears over it and nothing gets rid of the nits. Then I straight-ironed my little girl's hair and they disappeared after washing it. Think about it - we are advised to wash our clothes and bedding in temps higher than 60 degrees. Flat hair irons/strengtheners get to temps of up to 200 degrees. Try it - it really works!
