Head lice are small, wingless insects that are gray or brown. It is a parasite that feeds by sucking blood from the human scalp.
The size of newly hatched lice are about 1 mm (about the size of the head of a pin), and full adult louse is about 3 mm (slightly smaller than the size of a match head). Head lice take between 6 to 14 days to become fully grown, then the female will give birth to sexual relations and eggs on the scalp.
After seven to 10 days, the baby lice hatch and the empty eggshells remain glued in place. These remains are known as nits. Nits are white and become more noticeable as the hair grows and carries them away from the scalp. Sometimes it is thought to dandruff, but can be distinguished because it sticks to the hair and difficult to be deprived. Eggs take 7 to 19 days to hatch and remained on egg shells attached to the hair shaft. Lice can survive up to 21 days, and adult female can produce as many as 56 eggs in a relationship type.
