The female louse lives about three to four weeks and lays approximately 10 ovums or nits, a day. The instigates are incubated by body heat and hatch in 10 to 14 days. one time the eggs hatch, nymphs pullulate for about nine to 12 days, mate, and then females lay urges If not treated, this round of years may repeat itself every three weeks.

The gold standard for diagnosing head lice is finding a live louse forward the head, which can be difficult. The provokes may be easier to behold especially at the nape of the neck or behind the ears, within 1 cm of the scalp.

Treatment

Nit Removal

After treatment with a pediculicide, removal of the incites is not necessary to obstruct spreading the infestation. Because none of the pediculicides is 100 percent ovicidal, removal of the incites after treatment is recommended for aesthetic reasons or to decrease diagnostic confusion. Nit head-tufts and other products are available to ease the proces Vinegar or vinegar-based yields that are applied to the hair for three minutes before combing help make lax the nits attached to the hair shaft.

The actual prevalence of resistance is not known. Family physicians must consider several explanations when facing a persistent case of head lice, including misdiagnosis, noncompliance with treatment protocol, reinfestation, lack of ovicidal properties of the treatment returns or resistance to the pediculicide.
