Head lice are produced by lice that live in the head. Lice lay their eggs on a strand of hair, usually on the scalp. The eggs are very small and are hard to detect when they are first laid, but they will become noticeable after the second or third day. They are oval-shaped, brown, or tan in color, and are attached to the hair shaft.
They are spread through close physical contact and cannot fly. They can also travel on objects that come in contact with the head. Once they have fed, lice will move to another head within 24 hours. The easiest way to prevent the spread of head lice is to avoid contact with other people. Avoid sharing towels, hair brushes, or towels, as they can carry the parasite.
Lice eggs hatch within a week, and the lice larvae go through three growth spurts before reaching adult size. The life cycle repeats every three weeks. Lice feed on human blood several times per day, and secrete a substance that prevents it from clotting. If you have a child with head lice, you should remove their clothing immediately.
There are many home remedies and plant-based products that can be used to kill head lice. But despite these remedies, it is important to note that research is still needed to determine the effectiveness of these products. This is especially true of home remedies, since head lice have evolved to become resistant to insecticides.
