Nits of head lice also called pubic lice, need the heat and elevated humidity that is found next to individual skin to grow correctly. If nits are removed from this warm, moist location they will die. This is the reason they are mainly commonly found in close proximity to the skin.
Effective lice management begins with thorough nit subtraction. Live Lice or Louse can be eliminated quickly with the appropriate products. If the nits are not also removed a living infestation will come about rapidly starting the process over once more. Nits can be either physically removed or crushed. Lice combs do a good job of crushing nits in place or if lice combing is combined with one of the nit-loosening lotions found in several head lice home remedies, over the counter goods and products prescribed by physicians you can in fact remove nits without pulling hair out.
When juvenile lice hatch they leave behind the empty egg casing. The egg shell will stay still attached the hair shaft. This empty shell can stay put attached for weeks, or months so as the hair grows the empty shell moves further and further from the scalp surface. If left they develop into very evident. Many Mothers develop into what is known as "Nit Picky" and will pick the Nits from the hair of their children. A Nit comb will do this but if time is a factor and you want to remove them quickly it can be easily done by simply picking them off.
When searching for nits, any nits located further than approximately a 1/4" away from the skin it is most ordinary to find that they might have already hatched or they are dead. However, some recent study suggests that in warm climates lice will occasionally lay viable eggs further out on the hair shaft.
Color may be a superior way to discern blank or dead nits from live ones. Empty egg shells are white whereas live nits with lice inside are darker in color. The difference between live and dead nits is plain and easy to see. Getting rid of Head Lice Nits can be simple if proper preparation is taken and with a little patience.
