Head lice are obligate ectoparasites that live on humans. Their lifecycle only completes with human hosts. The head lice are found worldwide and can parasitize humans for prolonged periods of time. Head lice infestation is more commonly seen in unhygienic people, who do not change their clothes frequently. They feed on human blood and thus, cannot sustain for a long time without a host. The head lice spread is highly contagious and gets transferred easily from unclean clothes, combs, and towels.

Head contact is the most common mode of spread of head lice. Adult lice can lay 80-100 eggs and even more. Lice eggs are called nits, which look just like sesame seeds. The lice eggs (nits) are seen to cling to the hair shaft, which results in immense itching and hair fall. Nits may result in complete hair thinning and damage. Several hair treatments are available to cure head lice infestation. Personal hygiene is considered to be the most important factor that needs to be adopted by everyone in order to stop the spread. Keep on reading to know more head louse information and the various treatments available.
