There are many different ways that a person can become infected with head lice. It is most commonly spread from one person to another through direct head-to-head contact, although it can also be spread via clothing and personal items. While poor hygiene is not a cause of head lice, it can be the source of the infection in some cases.
The best way to prevent lice infestation is to use preventative measures. This means washing and drying all clothing and items that have come into contact with the person who has head lice. If this doesn’t work, you should take the problem to the doctor. You can also use an insecticide to kill the lice.
Lice live on the scalp for about 30 days and are less than an eighth of an inch long. They are not dangerous to humans, but they are uncomfortable. Head lice can be transmitted through personal items, including hats and towels. The lice will also infest a person’s hair if they are sharing the same bedding, towels, or combs. The infection does not spread to pets.
Adult head lice are the size of a sesame seed and are tan or grayish-white in color. They live for approximately 30 days on a person’s head and molt a few times over the next nine to fifteen days. The lice eggs are not capable of hatching at temperatures below the scalp.
