dr. lice
the reason you can't seem to get rid of lice is because you are not breaking the cycle. breaking the cycle is very simple using just a comb but not just any comb,the npa's licemeister is the best one.comb every day for at least two week's. no comb will pull babies off the scalp,you have to wait until they get five days old then the comb will get them. sometimes babies are hatching while you are combing keeping a cycle going. the only prevention for headlice is to comb once a week. stop using chemicals, it does no good and stop spraying your house,they are not in your house. lice only live a short time off the head plus they don't leave the head for any reason. I had a thousand live lice to research how long they live off the head most were dead around 10 to 12 hours all were dead in 24 to 28 hours how much blood and how old they were determined how long they would live just vacuum your house.I can help with headlice questions I do a lot of research with oils,mayo,vasolines,and just about anything else. I also developed a vaccum assisted equipment to help with removal
