A: I know this is old as in 3 years old but my son had a lice problem and we went to a professional to remove the eggs so I wanted to post a answer to this from what I was told from this pro. Rosemary or any kind of mint is a preventive BUT IT'S NOT A TREATMENT As this will not KILL THE EGGS YOU NEED THEM REMOVED BY A PRO! Also if you're looking for a everyday shampoo for preventive of lice this works as a shield barrier. The professional told me at the lice pro place said tea tree oil makes the hair itch even worse and is drying to the scalp. But again this can prevent lice as a protective barrier but should not be treated for the eggs as again will on kill the eggs. You need go to a PRO to remove the eggs because they've special treatment that kills the eggs and they use a special lice picking comb. Also fun fact water doesn't kill lice you need to put all pillows and wherever you or your child has been laying in the dryer on high heat. Lice can survive in the washing machine!
