Head Lice
Head lice are bloodsucking insects without wings. They are parasites that feed on human blood. Their bites may cause a scalp to become itchy and inflamed. Head lice and nits can more easily be found behind the ears, along the hairline and in the neck, as these areas are warm and dark. Lice aren’t dangerous and they don’t spread disease, but they are highly annoying and contagious.

Lice eggs (nits)
The head louse develops in three stages: egg (nit), larvae or nymph and adult. The female louse attaches the eggs to the hair with a kind of glue, no more than 1 mm from the scalp. Eggs stay firmly attached to the hair, which means that the distance from the scalp increases as the hair grows. After a maximum of 10 days, a nymph emerges from the egg. After a maximum of 12 days after birth, this nymph has become an adult louse. The total development from egg to adult louse takes approximately 3 weeks.

Head Lice Detection

Hair should be checked regularly, ideally once a week. A specific head lice comb can be used to check the hair on head lice, which is more effective than visual inspection. If someone detects a nit, this does not necessarily mean that the person is infested with head lice. Even when you treated your head lice with Licener, the dead nit can remain stuck to the hair until they grow out. It’s wise to treat head lice quickly once the diagnosis is made because they can spread easily from person to person.
