Overview of Head Lice (Head Lice)
Head lice are a very small form of the parasite, with grey or brown color, about the same size as the seeds in dragon fruit we often use. They lay eggs and after about 7-10 days of hatching eggs, grow rapidly and constantly increase in number if no preventive measures, destroy them.
Head lice live in hair, suck blood to grow and lay eggs. Nits are attached to hair by an adhesive secreted by the female lice. Nits are usually attached to the hair shaft about 0.5 – 1cm from the scalp.
The life of lice is about two months. During that time, female lice produce a lot of eggs but only about 50% of the eggs are live, the rest are small eggs.
Head lice live only on the human body and depend entirely on humans to survive. The life cycle of lice goes through three stages: adult lice, eggs and growing lice (also called cocoons).
Adult lice are about 5 millimeters long. Within 30 days, female lice can lay 130 eggs.  Adult female lice only need to mate with male lice once during the breeding period because they can store sperm in a special chamber on the body. In fact, throughout the life cycle, lice live on the hair, not on the scalp. They crawl down to the scalp about three times a day to suck blood and each ‘feed’ lasts about 15 minutes.
That’s why it’s hard to find lice on the scalp and it’s hard to find on the hair because the lice move very fast, at speeds up to 23 centimeters per minute. 
Head lice can live up to about three days if blood is not drained. So, if you can leave home for three days on a long weekend, you can make sure that your home will no longer lice except for some of the lice that fall around the house and that the lice are still living on your head.
