The first step to eliminating head lice is to apply a topical solution to soothe the itchy scalp. This will help relieve the itch and prevent the lice from returning. You should also consider a deep conditioner to replenish moisture lost through scratching. This will also reduce the itching and dryness.
After applying the solution, you should perform a lice check to ensure that there are no live lice or nits clinging to your scalp. If you find live lice, you can seek treatment for the infestation with the help of a dermatologist. Psychosomatic itching is another common symptom, and can last for days or even weeks.
Treatment is important as head lice are difficult to remove. Lice can live up to 30 days on the head if they are left untreated. The duration of the itching reaction varies depending on the number of lice. Medicated products kill lice quickly, eliminating them in two to three weeks.
The best preventative measure is to wash your hair, personal items, and clothing after contact with a person with head lice. You should also treat all household members who had contact with the person. Avoid sharing hats and stuffed animals with others. Always wash these items in hot water and dry them in the dryer. If you can’t wash the items, seal them in a plastic bag for up to two weeks. You can also soak hairbrushes in hot water to kill lice.
