How many lice are in one NIT?
After mating, the adult female louse can produce five to six eggs per day for 30 days (8), each in a shell (a nit) that is ‘glued’ to the hair shaft near the scalp (5,6). The eggs hatch nine to 10 days later into nymphs that molt several times over the next nine to 15 days to become adult head lice (5).
Can hair dryer kill lice?
A standard home blow dryer will kill 96.7% of eggs with proper technique. To be effective, the blow dryer must be used repeatedly (every 1 to 7 days since eggs hatch in 7 to 10 days) until the natural life cycle of the lice is over (about 4 weeks).
What color do nits turn when they are dead?
If the nit is dead, it will have collapsed into itself, and the sides will look crumpled. Check the color of the nit. Live and dead nits are brown; hatched nits are clear. If the color is brown, remove the nit right away and crush it between the fingernails before placing it in a plastic bag.

How do you tell if lice are old or new?
Nits that are freshly laid will be found near the scalp. When your child’s hair grows, the nits move further down the hair shaft and they are old nits. Nits normally will hatch in 7-10 days.
Will a hair straightener kill nits?
Heat absolutely does kill lice. The FDA-cleared AirAllé® machine uses heated-air to immediately dehydrate and kill lice and their eggs (nits). Straightening your hair can result in eliminating some head lice. However, this method will not completely get rid of all the lice and their nits.

Head lice eggs are oval, and the size of a pinhead. They are firmly attached to the hair shaft and cannot be brushed off. (A live egg will make a ‘pop’ sound if you crush it between your fingernails.) The easiest and most effective way to find head lice is to use the conditioner and comb treatment weekly.
