Nits also can be manually removed with any fine-toothed comb, including pet flea combs, a specialized nit comb (LiceMeister, LiceOut), a battery-powered vibrating or anti-static comb, tweezers, baby safety scissors, and fingernails.
When rinsing in the shower, take a nit comb with metal teeth and slowly come through all the hair to remove eggs.
In fact, the expression, "nit picking" comes from the struggle to free a person's hair from these parasites.
Pediculicides do not kill nits, so nit removal and a second application in seven to 10 days are required.
Regular lice checks in schools and "no nit" reentry policies have not been shown to be effective.
