The<unk>  is the removal of head<unk>  parasites from<unk>  hair. It has been debated and studied for centuries. However, the number of cases of<unk>  louse infestations (or pediculosis) has increased worldwide since the mid-1960s, reaching hundreds of millions annually. There is no product or method that assures 100% destruction of the eggs and hatched<unk>  after a single treatment. However, there are a number of treatment modalities that can be employed with varying degrees of success. These methods include chemical treatments, natural products, combs, shaving, hot air, and silicone-based lotions. Treatment is recommended only after a clear diagnosis since all treatments have potential side effects. Louse eggs hatch 6–9 days after oviposition. Therefore, a common recommendation is to repeat treatment with a pediculicide at least once after 10 days, when all<unk>  have hatched. Between the two treatments (Days 2–9) the person will still be infested with<unk>  that hatch from eggs not killed by the anti-louse product. Between the treatments, it is advised to wet the hair and comb daily with a louse-comb to remove the hatching<unk> . If no living<unk>  are found, the treatment was successful, even if nits (eggs) are visible on the hair. If living<unk>  are still present, the treatment is repeated using an anti-louse product with a different active ingredient. This is kept in the hair for 2 hours and then rinsed out, with the head and hair cleaned before sleep. Prophylactic treatment with pediculicides is not recommended.
