I have a daughter who is in her first year of kindergarten. One day my daughter came home with her hair so tangled and while I was combing her hair I noticed that she had lice and I will admit I freaked out and so I called my mom up and asked what was the best way to get rid of lice and she hung up and came straight over. I watched as she was putting olive oil in my daughters hair... All I could think was 'why olive oil?' but knowing that my daughter had school the next day I was willing to do anything to get rid of the bugs. I stayed up till four making sure that my home was lice free it took me an hour after I washed her hair out wit dish soap to brush it but I then rinsed her hair with white distilled vinegar and I saw such a difference it was amazing. I have never heard about tree oil till now but even now I check my daughters hair every night before she goes to bed.
In Florida head lice are almost a certainty if your children are in public school. Beware of head sets in the media centers and sharing MP3 headsets...it's just like sharing your comb.
After getting the head lice that wouldn't die, the kind that are resistant to the OTC stuff they tell you to buy, I found out that the cure of the desperate was petroleum jelly. Yes, that certainly did work however, it is just awful to try and get out of your hair! The next time the kids brought lice home from school, we tried olive oil. Generously douse the hair with it...work it in and put a shower cap on their head and leave it on as long as you can stand it, sleep in it if you can. The next morning, shampoo it all out, go over their hair with a nit picker comb and you are done with the lice. Check back every day or so to make sure none of the eggs are still in the hair. The oil simply suffocates the bugs. I have never had to reapply the olive oil. Added benefit, the olive oil leaves their hair really soft and shiny. While the hair is being treated of course, wash all the bedding in HOT water and spray the lice spray on the bed. Pack all their stuffed animals and pillows that can't be washed in a trash bag, tie it up tight and put it out in the garage for about two weeks to kill off the lice. They can't live without biting and they die of starvation!
EC: And if we might add -- people should always avoid using shared headsets, especially the ones found at the music stores that let you sample CDs before buying them.
