What should I do if I have lice in my hair? It's so disgusting

Comb with teeth

Using a good tooth comb is very helpful. A good comb can pull out head lice and lice eggs. We can find evidence of this from the ancient Egyptians - scientists have discovered combs specifically for removing lice eggs in ancient Egyptian tombs. The disadvantage is that it takes time and patience, and you have to do it over and over again until every last lice egg is combed out of your child's hair. The effect will be better if you comb your hair after washing it with medicine.

Shaving your head Head lice often grow on the hair, so as long as the hair is removed, there will be no space for the eggs and lice to survive. If a child or a man has head lice, shaving the head is the most effective way to get rid of lice. For the sake of their image, girls may not be willing to take this approach. If you don't want to shave your head, you can only use lice-killing measures. Even if you don't shave your head, at least cut your hair short and comb it thin so that it is easier to clean and remove lice. Then wash your hair with sulfur soap twice a day for a period of time, usually a few days, and you can completely kill the head lice. Home remedies for lice Some people say that mayonnaise, white vinegar, or tea tree oil are natural and effective lice removers. It is said that if you apply a thick layer of mayonnaise and put on a shower cap overnight, you can suffocate head lice. The purpose of white vinegar is to dissolve the glue that attaches lice eggs to the hair. However, these home remedies are not backed by scientific evidence, and pediatricians advise that there is no harm in parents adopting these practices, but they should not be used as the primary treatment method.

There are special medicines for killing head lice on the market. Camphor balls soaked in water or camphor liquid, 84 disinfectant, Stemona tincture, Bichongling, Disadi and other medicines can effectively kill head lice. Generally, one or two washings are enough. It should be noted that these are all toxic to a certain extent. When washing, do not let them come into contact with your eyes, let alone your mouth. If they do come into contact with your eyes or mouth, please rinse with plenty of water. Do not use shampoo, conditioner, mousse or other hair products within three days after killing head lice. To get rid of lice in the house, although lice cannot survive for long on the bed, it is best to wash bedding such as sheets and bedspreads. Clothes worn within 48 hours should also be washed in hot water. Some parents will also wash and disinfect the plush toys that their children have played with, but experts say this is unnecessary. If your child particularly likes to sleep with a stuffed animal, 20 minutes in the dryer may be enough to kill lice.
