You Have to Treat Them
Left untreated, head lice can lead to secondary infections, which can be serious. Bacterial infections, such as impetigo, can occur when scratched bites become infected; this can have serious consequences if not treated properly.
A louse can live up to a month if it can feed on blood several times a day. If lice fall off the scalp, they will die within a day or two. The female louse can lay up to 8 nits per day. The eggs hatch in about a week (6 to 9 days).
In fact, it can take up to six weeks for a child or adult to develop the typical itchiness that might prompt a head check. And even then, half the people with lice still won't exhibit any symptoms associated with lice.
OTC Treatments
Look for ingredients like ivermectin, which is effective with just one treatment, and doesn't require any nit-combing either. There are also prescription products that you can ask your medical provider for, that will help get rid of lice permanently and effectively.
Females are usually larger than males and can lay up to 8 nits per day. Adult lice can live up to 30 days on a person's head. To live, adult lice need to feed on blood several times daily. Without blood meals, the louse will die within 1 to 2 days off the host.
Then use a fine toothed “lice comb” to systematically work through the hair and remove adult lice. Regularly wiping the comb on tissues or paper towel will reveal the dispatched lice. This approach works but must be repeated twice, about a week apart, to break the life cycle of the head lice.
Head lice sometimes go away on their own because there are not enough insects to maintain the infestation, or they may persist for an indefinite period without treatment.
These children often spread lice to their families at home. The peak season for lice infestation is August through October and again in January. Head lice are tiny parasitic insects that feed on human blood. Lice come in three forms: nits (eggs), nymphs (baby lice), and adults.
Just like with mattresses, lice can only live on any bedding—whether it's sheets, pillows, or comforters—for 1-2 days. Without a human scalp as a source for food (blood) for longer than 1-2 days, lice cannot survive.
Since eggs do not need a host to survive, they will continue to live until a nymph hatches from it. A louse will ultimately die without a human host. However, it can still live for 1-2 days on a pillow or sheet.
DO LICE LIKE DYED HAIR? There is a myth related to hair dye: people with bleached or dyed hair cannot get lice. Lice gravitate as much to dyed hair as to hair that has not been colored. The bug only needs to climb up the hair to get to its food source, the head's blood.
How soon do symptoms appear after exposure? Some people may not have symptoms, particularly with the first infestation or when the infestation is light. It may take 4-6 weeks for itching to appear the first time a person has head lice. How are head lice spread?
After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2–3 days may decrease the chance of self–reinfestation. Continue to check for 2–3 weeks to be sure all lice and nits are gone.
Their bites can make the scalp itchy and irritated, and scratching can lead to infection. Head lice are annoying, but they're not dangerous and they don't spread disease. They're not a sign of poor hygiene — head lice need blood and they don't care whether it's from someone who's clean or dirty.
Formication is the sensation that insects are crawling on or under your skin when they aren't really there. It's one kind of a condition called delusional infestation or delusional parasitosis, which is a false belief about any infestation or infection.
Soak your child's head in olive oil or coconut oil. Cover with a shower cap for at least 2 hours (or preferably overnight). When ready, remove the shower cap, and separate the hair into small sections, then use a metal nit comb to carefully remove the lice and eggs.
Infested children usually carry fewer than 20 mature head lice (more commonly less than 10), each of which, if untreated, live for three to four weeks (5–7). Head lice stay close to the scalp for food, warmth, shelter and moisture (6,7).
What if I see live lice after treatment? Lice do not survive the Lice Attack Solution when it's done properly. However, if you don't follow the instructions (for example, if the treated hair was wet, very knotty, or not completely saturated with the Solution) lice could survive.
What kills head lice instantly? No methods have been found to instantly kill lice, though tea tree and lavender oil combinations in carrier oils have proven to be effective and time-efficient.
Lice don't always go away after one treatment and it could take a couple of weeks to completely get rid of them.
Head lice have no wings and do not fly or jump, but they can crawl or run through hair quickly. Most commonly, head lice are spread by direct head-to-head contact with an infested person.
Adult head lice can survive for 2 days and nits for around 1 week on a hairbrush. Soaking combs or hairbrushes in hot water of at least 130°F (54.4°C) for 5–10 minutes will kill any lice and nits.
