Head lice is an infestation of parasitic insects that lives on the scalp of people, often causing an itchy sensation. They can be a difficult problem to get rid of, but it can be done with a little bit of knowledge and patience.

Head lice can be spread through direct contact with an infested person or indirectly by sharing personal items such as hats, scarves, combs, brushes and hair accessories.

The first step in dealing with head lice is to identify the infestation. Head lice can be seen moving around or located near the scalp. They can also be identified by looking for nits, which are tiny yellow, clear or brown eggs secured to individual hairs.

The best way to get rid of head lice is to manually remove them from the scalp. This can be done by combing through the hair with a special fine-toothed lice comb to remove the insects and nits. Use a regular comb or brush to remove stubborn nits. Regularly check the hair for lice or nits to make sure that the infestation has been taken care of.

If manual removal isn’t successful, over-the-counter chemical treatments may be used. These treatments contain insecticides and should not be used on children under the age of two unless prescribed by a doctor.

Finally, it is important to keep the infested person’s hair clean and to wash, dry and store personal items separately. Vacuum carpets and upholstery to remove lice, and launder all bedding and clothing.

With a little bit of effort and patience, head lice can be eliminated. However, if the infestation persists, it is best to consult a doctor.
