I found this online. I don't know if it works or not- thought I would share anyway. So sorry to hear you are dealing with this. Kids get head lice at school so often around here.
Lay in a good supply of the items you'll need to complete the lice killing and removal process. For a person with shoulder length dreadlocks, three pounds of petroleum jelly, one gallon of vinegar, a large bottle of dish detergent and a large roll of plastic wrap should do the trick. Those with longer or shorter dreads can adjust the amount to their specific needs. It is very important not to skimp on either the petroleum jelly or the vinegar. It's better to have too much than too little.
Apply a liberal amount of petroleum jelly to dreads and scalp. Make sure each dread, each hair and every bit of scalp is covered with a thick coating of the petroleum jelly. For mid-length dreads, about eight ounces will provide the right degree of coverage. This does a few things. First, it coats the live bugs, slowing them down dramatically and making it easy to catch and remove them. Those that are not caught and killed by hand will suffocate. Second, it coats the eggs and prevents those from getting oxygen as well, which should prevent the vast majority from hatching.
After coating hair and scalp well and removing any visible lice, wrap hair and scalp in plastic wrap to prevent the petroleum jelly from staining clothing, furniture, and other items. Under ideal circumstances, the petroleum jelly should be left on for 24 hours. If that is not possible due to a work or school schedule, try to get at least 12 hours in.
Remove plastic from head and use dish detergent to wash petroleum jelly out of hair. Regular shampoo will not work. It will require three to five applications of dish detergent to remove petroleum jelly.
After washing out the petroleum jelly, soak dreads and scalp with vinegar. The vinegar helps to break down the lice eggs and the substances that allow the eggs to stick to the hair shafts. Wrap hair in plastic wrap again. Leave vinegar in hair for at least 12 hours.
Wash vinegar out of hair and carefully look for lice eggs, removing any that can be seen. Let hair rest for the remainder of the day.
Repeat the process--one day of petroleum jelly, one day of vinegar and one day of rest. That will bring you through the first week. At this point, all lice should be dead. However, if you missed a couple of the tiny eggs, seven to 10 days after the sighting of the initial lice, the eggs could hatch, starting your troubles all over again. Therefore, you will have to repeat this cycle two or three more times so that you disrupt the life cycle of the lice and ensure that they are indeed dead and gone.
