Head lice disease refers to a disease in which lice are parasitic in children's hair. The main symptoms are: scalp itching, especially when strenuous exercise or head is heated. Inspection shows that tiny white crystal lice eggs are closely attached to the hair roots. Unlike dandruff, it can't be easily removed. Head lice disease is an infectious disease, which is often caused by children's contact with lice carriers. Lice is a small insect that can fly to other people's scalp through contact. Adult lice lay eggs at the root of hair and hatch into lice two weeks later. Lice parasitize the hair and grow by biting the scalp and sucking the blood of the human body. When it bites the scalp, the child will feel itchy. Because lice make people itch and uneasy, and they are highly contagious, they must be cured in time. Prevention and treatment When a child is found to have head lice disease, parents can generally do the following work: If they find that the child is always scratching his head, especially when the head is heated, they should check the child's hair and carefully see if there are white crystal-like things attached to the hair roots that are not easy to remove. If you have seen lice eggs after checking your child's hair, you should go to the drugstore to buy a medicine to remove lice eggs. Wash your child's hair according to the instructions, and keep the medicine on your hair overnight to ensure that all the lice eggs can be killed.

The daily necessities used by children's heads, such as combs and hats, should be carefully cleaned with anti-tick detergent to avoid future troubles.
