Head lice can give you a hard time and severely cause your scalp to itch. Therefore, you must act immediately to prevent the possibility of infections. But, how to get rid of head lice?

Well, removing these parasites can be a challenge at times. However, many natural remedies and treatment options are effective in eliminating them. In this article, we will look at the best ways to remove and prevent head lice naturally and when you need to take medication. Keep reading.

What Causes Head Lice?

Head lice mainly spread through direct head-to-head contact, especially among family members or children who are in close contact at school or during play. Although less common, they may also spread through personal items like hats, scarves, towels, headphones, hair accessories, brushes, and pillows. Storing personal items together, such as hats on the same hook, may also cause lice transmission.

Contrary to popular belief, pets like dogs and cats do not lead to the spread of head lice. Children in preschool through elementary school are the most susceptible to head lice infestations due to their close interactions (1).

Once you have identified head lice, you must immediately work on eradicating them. We have discussed how you can do that in the section below. Check it out.

How Do You Remove Head Lice?

Depending on the number of lice one has and their skin type and allergies, there are several ways to remove head lice. Mentioned below is one among the easiest methods:

1. Check For Hair Lice

Most head lice treatment options tend to contain some pesticides. While they are not inherently dangerous, it is always better to use them sparingly. It also is important to determine you actually have head lice and are not mistaking it for some other hair issue (like dandruff).

  • Start by thoroughly drenching your hair and sitting directly under bright light, either in the sunlight or under a bright lamp.
  • With the help of a rat-tailed comb, divide your hair into thin sections and pay close attention to your scalp. Lice are grayish-brown insects that can be spotted easily.
  • Search for white head lice eggs or nits. These eggs attach themselves to the hair strands.
  • Removing the substance and pressing it between your gloved fingers can help you differentiate lice eggs from dandruff. If you hear a faint, sharp sound, you are holding an egg. If not, you probably have dandruff.
  • Use your fingernails to pinch the hair strand directly beneath the white flake or egg, and pull it up on the hair strand tightly. If it comes off the hair, it is dry skin; if not, it is a lice egg.

Step 2. Shampoo Your Hair

The easiest way to get rid of hair lice is by washing your hair with a delousing shampoo. This product contains mild pesticides that help kill the lice.

If you notice eggs in your hair, we recommend using ovicides a type of shampoo specifically designed to kill both the lice and their nits.

That said, ovicides are not recommended for individuals with:

  • Dry, flaky scalps
  • Sensitive scalps with a history of allergies
  • Injured scalps that are either bloody or crusty

If you have any of the aforementioned issues, check with your doctor before applying any product to your hair.

Step 3. Remove The Lice And Nits

  • With the help of a rat-tailed comb, divide the hair into several thin horizontal sections, starting from the crown and ending at the back of the head.
  • Run a fine-tooth nit comb through each section of your hair.
  • Clean out the dead lice and eggs from the comb before moving onto the next section.

Repeat this process at least thrice before your next hair wash.

Step 4. Repeat The Process

Repeat the shampoo-and-combing process all over again. Be sure to wash your clothes after each step to keep any fallen nits from entering your hair again. But if the lice persist even after two hair washes, we suggest you visit a doctor.

Head shaving is not an appropriate solution to eliminate lice, as the baby lice (nymphs) embedded in your scalp will eventually develop into adult lice and multiply.

While using a delousing shampoo is the most effective head lice removal method, several people may not have access to it. Read the next segment to find out how you can get rid of head lice naturally.

Removing Head Lice And Eggs Naturally

Unsurprisingly, you can also kill head lice with several products at home. Some of them are as follows:

1. Anise Oil

Anise oil is considered effective in removing head lice and nits in children (1). The liquid works by suffocating the lice and killing them. This herbal oil is also believed to aid in head lice prevention and stop lice reinfestation.

2. Olive Oil

Olive oil may also help remove head lice in ways similar to anise oil (2) By suffocating the head lice, this oil may help prevent re-infestation. People typically use a mixture of anise and olive oils for better results. You can also mix one to two drops of rosemary essential oil with your olive oil and apply it to your scalp for treating head lice (3).

3. Coconut Oil

While not as effective as anise or olive oils, coconut oil is also a good solution to one’s head lice woes. Researchers compared the effectiveness of coconut oil with other over-the-counter medications. According to the results, coconut oil had an 80% effectiveness rate, whereas delousing shampoos had a 97.9% effectiveness rate (4).

Now that you know how to get rid of hair lice naturally, let us move on to medical treatments.

When Is Medication The Most Effective Way To Get Rid Of Head Lice?

As of today, delousing shampoos and lotions are undoubtedly the best methods to get rid of head lice. We, therefore, recommend using them before trying any other home remedy.

There are two types of over-the-counter delousing shampoos available on the market. They are:

1. Pyrethrins Delousing Shampoo

This delousing is made of an extract of chrysanthemums. It falls under a class of medication called pediculicides. The product can be used on individuals who are above the age of 2 years.

Typically, this shampoo needs to be used twice, seven days apart, to ensure the newly hatched lice are also killed. Do note, however, that this product is not meant for those who are allergic to ragweed and chrysanthemums.

2. Permethrin Lotion

A major drawback of the Pyrethrins delousing shampoo is that it can only kill the lice and not their eggs. As an alternative, many people opt for Permethrin Lotion, which eliminates the lice as well as their nits. It is safe for anyone over 2 months old.

This product does not wash off easily and instead leaves some residue on the hair. This, in turn, kills the newly hatched insects, thereby eliminating the head lice infestation completely.

That said, do note that your regular shampoo and conditioner may impact the effectiveness of this product. Therefore, you must re-apply the lotion after 10 days to completely eliminate lice infestation.

The Pyrethrins delousing shampoo and Permethrin lotion can be used on children. But many doctors recommend avoiding the application of medical treatments on any child under the age of two years. They instead suggest different herbal oils such as anise, coconut, and Olive to eliminate the infestation.

Consistently maintaining your hair is the best way to rid yourself of head lice and avoid re-infestation. Read the next segment to know more.

Post-Treatment Care For Head Lice

To avoid re-infestation, make sure you do the following:

  • Use a head lice comb to brush out the dead lice or nits 8 hours after you apply the treatment.
  • Soak all the combs, clips, and other products you use in boiling water for 5 to 10 minutes. This will ensure all the nits are killed.
  • Wash your used clothes in either hot water or put them in the washing machine to kill the nits and insects that may have fallen on them.
  • Do not shampoo your hair for 2 to 3 days after using the product. This will give the treatment more time to work on your hair.
  • Check for nits and lice once every three weeks. If you find any, take corrective action immediately to avoid re-infestation.

Bear in mind that these treatments may not always give you the best results. What should you do in that case?

What If The Treatments Do Not Kill The Head Lice Fast?

In certain cases, over-the-counter treatments may not work. The reasons could be:

  • The lice are too strong
  • You have not followed the right usage instructions
  • You have not applied the product at the right time

At this point, it is wise to approach your doctor to conduct a basic hair evaluation. They will either show you how to efficiently eliminate head lice with the help of other over-the-counter treatments or prescribe stronger medications.

You can also prevent lice infestations with a few tips and tricks. Read the next section.

Ways To Prevent Head Lice

1. Do Not Share Personal Belongings

For the most part, lice can move from scalp to scalp through their personal belongings (especially those used on the head). Hence, limit the number of personal items you share with others. These include:

  • Caps
  • Helmets
  • Clothes
  • Earphones
  • Combs and brushes
  • Scarves
  • Jewelry and hair accessories

2. Use Appropriate Hairstyles

Hair-to-hair contact enables the lice to move from one scalp to another. Thus, you must contain your hair as much as possible. You can do this by braiding your locks and applying some styling spray to hold your strands in place.

3. Oil Your Hair

Oils such as coconut, olive, and anise protect your hair against infestation by suffocating the lice. Applying oil to your hair regularly may also prevent its spread.
