Hair is said to be the beauty of the face, and what a mess happens when lice reside in them. Generic name of head lice is “Pediculus humanus captis”. They are the parasite that feed on the blood and exist only in the hairs. They lay their eggs on the head and adhere to the hair near the scalp. They are spread very easily and fast through the objects like comb (using same comb), hairbrushes, hair bands, head phones and related items, as the lice can survive till 2-3 days away from the scalp. Eggs too are resistant and can live for 2-3 days but they particularly need humid atmosphere to grow. Usually head lice occur more often in schoolchildren as they are for long time in close contact with each other and often unknowingly use shared brushes and combs. Many a times lice are present in other parts of the body usually covered with hair, these are usually not head lice rather they may be pubic lice (generic name: Pthirus pubis) or may be body lice (generic name: Pediculus humanus humanus)
