Do lice go away on their own? While head lice infestations can be frustrating and inconvenient, it's important to note that they don't resolve on their own and require treatment for elimination. "Without intervention, lice can reproduce and persist," says Dr.
Adult lice can live on a person's head for about 30 days. However, they will die within two days if they fall off a person and cannot feed. Adult female head lice are usually larger than males and can lay about six eggs each day.
Generally, if no live crawling insects are seen three weeks after the treatment, it's safe to assume that they are gone. Nits would have hatched by that time if they were alive. Nits and their shells may remain in the hair for some time but won't be viable.
A person will need multiple treatments to eradicate head lice, and this can take around 2–3 weeks. Head lice are around 2–3 millimeters (mm) long and are often visible to the naked eye. They live on human heads and lay eggs at the bottom of hair shafts.
Tea Tree Oil. Though many people are sensitive to tea tree oil, it has been shown to be effective at killing lice. One study showed a 100% mortality rate after 30 minutes of treatment. A tea tree oil-scented spray or shampoo may be useful in preventing reinfestation.
Use heat. Wash any items used or worn by the person in hot water, and dry them on high heat. Lice and nits die when exposed to temperatures higher than 130 F for more than 5 minutes.
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- re-infestation. Continue to check for 2-3 weeks to be sure all lice and nits are gone. Retreatment is meant to kill any surviving hatched lice before they produce new eggs.
Lice require human blood to survive and are unable to live for an extended period away from a human host. While lice may temporarily crawl onto bedding, they typically do not survive on the bed for more than 24 to 48 hours. Without a human host to feed on, lice will eventually perish.

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. It's best to treat head lice right away to prevent them from spreading.
The reality is that any adult who has hair can get head lice. However, it is incredibly rare for adults without children to get head lice. One of the major reasons for this is that people typically do a good job of controlling head lice.
After the first treatment, when the egg-laying lice are eliminated, you are no longer contagious.
Research suggests that bed linen, hats, clothing and furniture do not harbour or transmit lice or nits and that there is no benefit in washing them as a treatment option. Nits and lice only live on the human head. They quickly dehydrate and die if removed from the head.
Lice cannot “fall” on pillows, sheets, stuffed animals, and other bedding unless the hair that they are attached to fall. But they can't live on these surfaces, or on hats, scarves, furniture, or carpet.
When a person has head lice for the first time, itching may not occur for 4 to 6 weeks. Lice on scalp. You may be able to see the lice, but they're often hard to spot because they're small, avoid light and move quickly. Lice eggs (nits) on hair shafts.
Spinosad (Natroba).
Spinosad is approved for adults and children age 6 months and older. It can be applied to dry hair and rinsed with warm water after 10 minutes. It kills lice and nits and usually doesn't need repeated treatment.
With effective treatment, head lice will completely go away after two to three weeks. The duration is dependent on how many lice made a home in your hair. Make sure you follow the instructions on your medicated shampoo, lotion or cream to get rid of lice quickly.
Lice can look like dandruff or other conditions of the scalp. Identifying head lice often depends on spotting the nits (eggs), which look like tiny yellow, tan, or brown spots stuck on the hair shaft near the scalp.
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.
Lice can be tricky to get rid of because nits can remain unhatched on your head or you might pick up lice that are still on bedding or other items. Here's what to do if you've had lice — or someone in your family has: Wash bed linens and clothing that anyone with lice has used recently.
