Head lice are tiny bugs that feed on blood from the human scalp. They lay eggs, also known as nits, which attach firmly to strands of hair. These nits hatch and grow into lice.
Lice can grow in an unhygienic and unhealthy environment. Once they start growing on someone's scalp, they can spread easily to the people around them. Lice have the ability to run up to 9 inches per minute. The transmission of lice happens by directly coming in contact (head to head) with an infected person or by using their hair accessories and combs.
Pediculosis capitis is a medical condition where the lice spread and grow in the hair and scalp of a person. The symptoms of pediculosis capitis can be constant itching, tickling sensation on the scalp and sores on the scalp due to scratching.
The medical treatment of head lice involves the use of pyrethrins with piperonyl butoxide, permethrin, malathion, benzyl alcohol and spinosad. These are available in the form of soaps, shampoos, lotions and gels. While most of them are available over-the-counter, some of these need a medical prescription.
Head lice can also be treated at home with basic things available around you. Here is the list of home remedies that can help in removing lice from the head.
