How quickly lice grow on the head, the life cycle of development

By Lice Clinics of America

Understanding the life cycle of head lice is an important step in knowing how to treat lice infestations, and what your expectations should be depending on the type of lice treatment you use.

Head lice start as eggs (also called lice nits ) that are glued to a hair shaft about a quarter inch (

0.5 cm) from the scalp (view lice egg pictures ). Because of their protective shells, eggs are quite resistant to many lice products that use pesticides , essential oils or suffocation as a means of killing the lice. This is why lice shampoos and similar products often require additional treatments a week or so later, to treat the new lice that hatch from the unaffected eggs.

Lice eggs are attached well enough to the hair that they can withstand fingers, hair washing, brushes and everyday activities; however, if used properly a lice comb can be an effective way of removing lice eggs.

One of the benefits of using a dehydration product like AirAllé ® to treat head lice is its high effectiveness at killing lice eggs (99.2 percent effectiveness).

Eight or nine days into the lice life cycle, a nymph will emerge from the egg. Nymphs are very small and like to stay close to the scalp where they feed. Nymphs will spend 9-12 days growing into adult lice, at which stage they can reproduce.

An adult louse is about the size of a sesame seed (see head lice pictures ). They can be found traveling farther along the hair than nymphs, which means they are more susceptible to falling off the hair, or climbing onto another head through hair-to-hair contact.

Adults live up to 30 days on their host. Females lay roughly four eggs a day, or roughly 88 eggs during their lifetime. People get infested with head lice when a female louse transfers to their head and starts laying eggs.

Life Cycle Of Lice: How Long Does It Take for Lice Eggs to Hatch?

A Middlesex County mom, Lisa G., called LiceDoctors a couple of weeks ago to say that she and her kids had been exposed to head lice and she was pretty sure that they now had nits (eggs) in their hair. She wanted to know at what point should she expect those nits to hatch. The question is a good one; as soon as the first round of nits (lice eggs) hatches, you have a second generation of lice. Each louse lays 6 to 10 eggs a day before it dies 30 days later. Once that happens you can see how the initial louse has multiplied and eventually has yielded hundreds of lice. We explained to Lisa that it takes 8-12 days for nits to develop and hatch. To have nits, you have to have had a bug in our lice treatments attack lice at all stages of development the hair; you can’t catch nits. While it typically takes about 1 week to 10 days for eggs to hatch, the first few days after a nit is laid it is too small to be seen.The point is that when you see nits in the hair, they have already been there for days and could hatch at any point. While the LiceDoctors treatment plans work no matter how many bugs or nits are in the hair, it is obviously better to find a case early.

Once a nit hatches, a baby bug or nymph comes out. That nymph takes about a week to 10 days to mature into a louse that is mature enough to lay eggs. During that time, scientists measure it 3 times as it grows noticeably bigger. A louse can lay 180-300 eggs before it dies. Young Girl Scratchign Her HeadThe life cycle of lice continues until all of the bugs and nits are removed from the hair. If you leave nits in the hair they will hatch and the case will continue to get worse. Lice cases do not go away by themselves. You will likely start to itch again. If you have been exposed to head lice, it is never too early to be checked. If you have contracted lice, chances are there is still a bug and there may be nits, as well, in your hair. If your lice technician finds head lice, she will remove the bug(s) and nits before your case gets worse. We are just a phone call away at 609-722-7143.

How Long Does It Take for Nits (Lice Eggs) to Hatch?

A mom called us from Tucson a couple of months ago to say that she and her kids had been exposed to head lice and she was pretty sure that they now had nits (eggs) in their hair. She was leaving for the weekend and wanted to know how long it would take for those eggs to hatch. Basically she wanted to know if she could hold off on picking out the nits until she returned home in two days. We explained to her that it takes 8-12 days for nits to develop and hatch. The catch is that you do not know for sure how long the eggs have been in the hair. In order to have nits, a bug has to have been in the hair. You can’t catch nits; they must be laid by a bug. While it typically takes about 1 to 2 weeks for eggs to hatch, the first few days after a nit is laid it is too small to be seen. The point is that when you see nits in the hair, they have already been there for days and could hatch at any point. While the LiceDoctors treatment plan works no matter how many bugs or nits are in the hair, it is obviously better to find a case early.

From Louse To Nit

Once a nit hatches, a baby bug or nymph emerges. That nymph takes about a week to 10 days to mature into a louse and start to lay eggs. A louse lays up to 6-10 eggs a day and can live 30 days before it dies. That means each bug can lay 180-300 eggs before it dies. The life cycle of lice continues until all of the bugs and nits are removed from the hair. If the head is not effectively treated the case will continue to get worse. Lice cases do not go away by themselves. LiceDoctors offers a safe, all-natural treatment that will leave you lice-free.

What Happened to Tucson Mom?

By the way, the Tucson mom did decide to continue with her plans for the weekend. We arrived at her house late Sunday night and we found some nits and a few live nymphs; apparently, the nits had been there for at least a week and had therefore hatched. We eradicated the problem and she was grateful that we treated the case before it had a chance to advance any further. Learn more about our Tucson lice removal treatment now!

Lice are parasitic insects that feed on human blood. They are a common nuisance to school-aged children. Though lice do not transmit illness, they do reproduce at an extremely fast rate and are highly contagious. Despite popular belief, lice cannot fly or jump, but they do crawl extremely fast. The lice eggs are more likely to be seen than the bugs themselves, depending on the level of infestation.

Size of Adult Louse and eggs

An adult louse is about the size of a sesame seed and is yellow to brown in color. They have six legs and can reach maturity in nine to 12 days.

Lice eggs, also known as nits, are the size of a period, but oval in shape. They are attached to the hair shaft with a glue-like substance which makes them hard to remove. They are typically attached at an angle and can vary in color depending on what stage of life they are in, but usually range from translucent brown to yellow, to tan.

LIfe Cycle

Only one live bug can be produced per nit or egg. After the egg is laid, it takes roughly seven to 10 days for it to hatch.Once the egg hatches, it takes another seven to 10 days to reach maturity and begin laying eggs of its own. An adult louse can lay up to six eggs per day and live for up to 30 days on a host. Pets cannot get lice.

A live louse cannot live for more than 24-48 hours off of its human host. It needs to feed and sustain its warmth otherwise it will die.

Nits can live a bit longer and are harder to locate and remove, which makes treatment so difficult.


Pesticides are commonly used to treat lice. Several different varieties are available on the market. It’s important to read the labeling to ensure you are getting both a pesticide (one that kills the live lice) and an ovicide (one that kills the eggs). Common problems are associated with people just using pesticide and assuming that it kills the eggs. If pesticides are used, then it is imperative that the infested head be combed with a lice comb and examined thoroughly to make sure no nits remain. If just one nit is left on the hair, it could hatch and the process will start all over again. A second treatment is recommended no more than 10 days after the initial treatment to ensure everything has been killed. Examples of over-the counter products are LiceMD, Licefree, RID and Nix.

Home Treatments

Talk to any parent, and they’re likely to boast about home treatments they have developed or used. Use of mayonnaise, oil and Vaseline are common home treatments. Those are used with the idea that the dense product will “smother” the lice.

Natural Remedies

There are a few natural products that are pesticide free. One is tea tree oil as well as eucalyptus. Those are typically used as preventive treatments because it is believed that lice are repulsed by the smell.


Lice infestation is commonly and incorrectly thought of as a “dirty person’s” affliction. That cannot be further from the truth. Lice are actually drawn to clean hair, that is easy to grasp onto (as opposed to greasy or product filled hair). Washing your child’s head every day will not prevent lice because they are not easily washed away with water or shampoo. In fact, when a louse lays its eggs on the hair shaft, it has special “glue” that adhere the nit to the shaft. It is so powerful that it makes nit removal that more difficult.


For children with longer hair, braids and pony tails should be considered. Shorter hair cuts are a great option. Keeping the hair away from sources that potentially have lice is another way to help prevent infestation. Checking your child’s head a few times a week, especially behind the ears, the crown and the nape of neck, is crucial.

How to Remove Lice Eggs from Hair in One Day: Naturally & Quickly

What are the artificial or natural ways to remove lice eggs from the hair within 24 hrs? This article attempts to answer this question as clear as possible. As we all know, lice are notoriously difficult to get rid of more so if they have already laid eggs and have nymphs crawling on your scalp.

The bad part about lice is that it only takes two weeks to complete a life cycle meaning if there is an egg attached to the hair shaft, it will take about two weeks to hatch, grow, become an adult and lay eggs as well.

Time is always crucial when dealing with lice. But luckily, there are solutions that can help you get rid of lice in a day or so. They come in both natural and artificial ways.

How to tell if you have lice by yourself

The good thing about, that is if there is, is that you will know that you have them. It will not take long before they advertise their presence in your hair. They are not some smart creeping bugs that go undetected.

You do not need to visit your doctor to know that there could be some tiny bugs pitching a camp in your hair and sucking your blood away whenever they want.

Here are some symptoms that strongly suggest that your hair could already be a breeding ground for lice.

  • An itchy scalp. When lice crawl on your scalp or bite to draw a blood meal, you will definitely feel it in the form of itch. You may need to pay attention beyond the usual scalp itch that could be from something else.
  • If you scratch yourself on the head quite often than normal, then chances are that you got lice in your hair.
  • Crawling sensation: Your skin is full of receptors that can notify you with accuracy if a sensation is due to something crawling on your skin. If you feel like something is crawling in your hair, then it could be lice.
  • Seeing bugs or nits: At times, a louse or a nit may be dislodged from your hair and fall off, more so if their numbers are swelling. If you see pale oval fragments or a bug of between a quarter to a third of a centimeter or tiny drop from your hair, then it could be a louse.
  • Swollen lymph nodes: Your body reacts when something is causing pain or distress such as persistent itching or bites from bugs. If you feel some pain and lumpiness in the upper neck, it could be that your body has sensed distress caused by lice.
  • Pink eye: A pink out of nowhere could indicate something that is happening to you that you have not cared to find out. It could be the lice in your hair, or some other bug.

Small tiny bugs in hair, but not lice – what could they be?

The symptoms above may be expressed for some other tiny bugs other than lice. If you are not sure which bugs are crawling, breeding, living, or chanced on your hair, then visiting a dermatologist would help you know which ones are already in your hair and which ones are not.

There are very few bugs that can be found in your hair. Some simply find themselves in your hair while others survive by invading your hair and scalp.

  • Mites: Other than lice, hair mites can cause a nagging irritation, especially at night. Unlike lice, mites actually burrow in the skin around the hair follicles. They could go as deep as 3 cm just to lay their eggs. They cause scabies which will need a comprehensive medical exam before treatment.
  • Ticks: Another suspect bug that could have taken refuge in your hair is a tick. Ticks are found outside “chilling” on leaves and grass just waiting when you will pick them up without knowing. They like taking refuge in folds and in the hair where they burrow their mandibles and suck their time away.
  • Chance crawlers: Sometimes it is not a parasitic bug that is causing the itching and crawling sensation in your hair. It could be an insect or another bug that found its way in your hair by chance while you were out in the open. It could be insects or aphids. These crawlers are not looking to make your hair their home. You can call them passer-by crawlers.

How does a Lice Egg look like?

So you have heard of lice and suspect that they could be in your hair already. Or, you just want to know how their eggs look like in case you encounter one and need to take quick precautions. A lice egg is tiny and chances are you were near one and missed it.

A Lice Egg

It is typically oval in shape, ranges between yellow and white in color, and is between 0.3mm and 0.8mm.

At such a size, anything will almost look like a lice egg if it bears the same color.

You may need a magnifying glass to confirm it is a lice egg.

However, if you notice such objects on your comb after passing it in our hair, the chances are that they are lice eggs.

Do not be intimidated by them. There are natural ways of killing those eggs.

What kills Lice Eggs Naturally?

Conventional methods of dealing with lice are not recommended for the basic reasons that either they do not work or are simply toxic for use. Some of them contain toxic active ingredients that may have a detrimental effect on you after use.

Fret not because there are natural solutions to getting rid of lice eggs which include.

  • Heat: lice eggs are not resistant to heat that is excessive for example from your blow dryer. You can use heat effectively to kill the eggs without extra costs on you.
  • Essential Oils: There is a range of essential oils that kill lice eggs naturally without you having to stress with shelf products. They include jasmine, olive, lavender, tee tree oil, ylang ylnang, and anise oil among many others.
  • Mayonnaise: As much is it looks weird, that mayonnaise seated in your kitchen cabinet could be your gateway to a lice-free hair. Its contents, specifically the fats and the vinegar are good in killing lice eggs if left in your hair for over eight hours.
  • Apple Cider Vinegar: A 50% solution of vinegar in water is effective against lice eggs and is known to kill them if left in your hair for more than eight hours.

How to Get Rid of Lice Eggs in Hair Fast

You should know by now that using a chemical agent against lice eggs takes hours because they are glued on the hair shaft and have tough exoskeletons that are mostly impervious to a broad range of the chemicals.

There are two proven ways that you could use to rid your hair of lice eggs almost instantly.

  • Using a Compact Comb: If eggs are glued to the hair shaft, then why not pull them out by force? Using a compact comb will help you tear away the eggs from the hair shafts as immediately as you pass it through your hair.
  • Use Heat: Plug in your blow dryer into the wall outlet and push the “hot” button to begin blowing your hair. The lice eggs would simply die because they cannot take the heat. Divide your hair into small heaps and blow each heap for 30 seconds.

How to use Tea Tree Oil for Lice Eggs

Tea tree is a wonder plant and its oil can virtually be used for any extern health concern including dealing with lice. There are many ways you can use tea tree oil as the ingredient of choice to fight off lice.

Some recommend using tea tree oil with another agent such as a conditioner or a shampoo which is fine. You could also use pure tea tree oil to see for yourself if this is the method of choice.

The following is a procedure that you could use with pure tea tree oil diluted in water.

  1. Dissolve tea tree oil in water to make a 2% to 5% solution.
  2. Carefully saturate your hair with the solution. Pay more attention to the hair borders, behind the ears, and at the back of your head. Live to love such spots.
  3. Wrap your head with an impervious head cap.
  4. Leave overnight or for at least 8 hours if you prefer staying awake.
  5. Use shampoo or hair to wash your hair and rinse with cold water.
  6. Repeat the same procedure twice or thrice a week.

P.S.: Make sure you only use the dissoluble version of pure tea tree oil. Otherwise, the method may not be effective.

Conclusion on Lice Eggs Removal

Lice are bothersome bugs and only take two weeks to conquer your hair and scalp. Swift action against them will be the only way you can keep them from becoming menacing and passing them to others. Getting rid of their eggs is notoriously difficult.

However, there are natural and artificial ways of removing or killing them. If you have no haste and need to take your time, then use a natural remedy that is known to be safe such as tea tree oil, apple cider vinegar, and mayonnaise.

If you need an instant solution to the bed bug problem, then a comb or a blow dryer is probably the best solution.

Life Cycle of A Sea Turtle

The sea turtle life cycle starts when a female lays its eggs on a nesting beach, usually in the tropics. From six weeks to two months later (depending on the species), a tiny hatchling makes its way to the surface of the sand and heads to the water, dodging every predator imaginable.

what is the sea turtle life cycle?

Baby turtles (or hatchlings) start out as eggs that are laid in nests on beaches around the world. Once ready to hatch, they break out of the egg with an egg tooth (called a “caruncle”) and move slowly up the sand until they get to the surface and then head to the water.

As young (or juvenile) turtles, they head out to sea. From there, in many cases, we don’t know where they go (that’s why we call them “the lost years.”) Some turtles born on the US East Coast head out to an area called the sargassum sea, a large area with seaweed known as sargassum, where they feed and grow.

Once they are fully grown, they head back to where they were born to mate. Adult females will mate with multiple males and then when ready, the climb up onto the nesting beach to lay their eggs, starting the cycle again.

Sea Turtle Nesting

Sea turtles around the world nest on beaches in warmer places (tropical and sub-tropical beaches.) The female goes ashore, digs a body pit then and a nest (or egg chamber), lays the eggs, and finally covers up the nest. After that, they will camouflage the nest, covering a big area with sand, to hide the nest, and then head to the water. About six or seven weeks later, the hatchlings will emerge and then head to the water.

«The Lost Years»

From the time the hatchlings take their first swim until they return to coastal waters to forage as juveniles may be as long as a decade. This period of time is often referred to as the «lost years» since following sea turtles movements during this phase is difficult and their whereabouts are often unknown.

Following the «lost years», when they have grown to approximately the size of a dinner plate, their pelagic (open ocean) phase comes to an end and they return to coastal waters where they forage and continue to mature. During this time, these reptiles are highly mobile, foraging over large areas of ocean.


Ten to fifty years after hatching (depending on the species), adult sea turtles reach sexual maturity and are able to mate. Once they reach sexual maturity they will migrate to beaches around the world to nest. Only females will come ashore to lay eggs, generally in the area where they were born. Most species will nest several times during a nesting season every 2-4 years over the course of their lifetime.

It is not known exactly how long sea turtles live in the wild, but scientists think their life span may be as long as a century. Unfortunately though, turtles face a multitude of threats related to human activities. For more information about the challenges they face, see our pages about threats to sea turtles.

The Circle of Lice

Also known as Pediculus humanus capitis, head lice are a common, but misunderstood nuisance. We know that there’s a lot of stigma regarding head lice, and we’re doing everything we can to clarify misunderstandings and help people gain a better understanding of what lice are and are not. Today’s post is going to take a look at the stages of lice development, or as we like to call it, the Circle of Lice.

The Stages of Lice Development

Lice begin their journey in an egg. These eggs are also known as “nits,” and you might hear this term used at our Houston lice treatment center. Nits are laid by adult female lice and are almost always found close to the scalp. In most cases, they are planted at the base of a hair shaft. They are incredibly small, with most eggs measuring approximately .8 millimeters by .3 millimeters. Between their small size and white-yellow coloration, it’s no surprise that many people mistake nits for dandruff. These eggs typically hatch after six to nine days and develop into nymphs, which we will discuss in the next section.


Once an egg has hatched and released a nymph, the shell remains attached to the scalp and turns a dull shade of yellow. Nymphs are approximately the size of a pinhead, which makes them difficult to spot in individuals with longer hair. They grow quickly and reach adulthood after approximately a week, at which point they begin feeding several times each day. This is also the point at which many people begin to feel the sensation of lice in their hair.


Adult lice are between 2 to 3 millimeters in size, or approximately the size of a sesame seed. They’re still difficult to spot with the naked eye, but they can be seen if you’re looking closely. Adults can live for up to 30 days, and females can lay up to 8 nits per day. That means that each female louse on a person’s scalp can lay up to 240 eggs in one lifetime! At that rate, it’s no surprise that lice infestations get out of hand so quickly.

Head Lice: How You Get Lice and How to Tell If You Have Lice

Head lice are very small insects. Adult lice are about 1/10 to 1/8 of an inch long. They thrive on the scalp due to the warm, moist environment. As parasitic insects, they survive by feeding from the blood supply to the scalp.

How Do You Get Lice?

Contrary to popular belief, having head lice isn’t a sign of bad personal hygiene. You could have the most impeccable personal hygiene and still get head lice. It is one of the most communicable diseases, second only to the common cold.

Lice are usually transmitted through direct contact with someone else who is infected. Once lice have been removed from the scalp, they become dehydrated and die. However, they can survive for up to 3 days on hats, combs and brushes. They can be spread through the sharing of these items, although this is rare. It is also another myth that lice can jump. The idea that they can probably stems from lice being flicked off by static electricity while dry hair is being combed. However, infection most commonly occurs through brief head to head contact, as lice can crawl at a very fast rate of nine inches per minute through the hair.

How Can You Tell If You Have Lice?

Lice are usually noticed when itching begins, although infestations can begins 2 to 3 months before any itching occurs. The itching is usually no due the bites from the lice, but due to an allergy. Itching commonly happens around the ears and at the back of the head.

There is no other way to find lice than to actually look for the lice or any traces. You can begin by parting the hair in different sections around the head and look out for:

  • Live lice — These will commonly be around the ears and at the back of the head. Lice tend to move very quickly away from areas that are being disturbed so they can be easy to miss. Alternatively, you could try using a lice comb. You can purchase these from any chemist. Dampen the hair and put conditioner in it. Then, comb through it in sections, from root to tip. Regularly wipe the comp on tissue paper and inspect it. This damp hair method works better as lice tend to stay still when the hair is wet. Using the conditioner and normal comb will work just fine.
  • Live eggs — Lice, also known as nits, are attached very tightly onto the hair shaft. They are oval shaped and usually located ½ an inch from the scalp. Unlike dandruff, nits remain attached to the hair shaft even after they have hatched. Since they are so small, they are easily mistaken for dandruff. Using a magnifying glass and good lighting may help.
  • Black specks — Lice feces appear as black specks. They can be found in the hair, on pillows or collars.
