Preventing and Combating Head Lice Naturally

Applied as a hair mask or as an oil mask before showering, certain carrier oils are formidable lice killers.

• Coconut carrier oil (melt beforehand if necessary), applied evenly all over the hair, penetrates the lice's respiratory tract. It acts as a natural anti-lice agent, coating the lice and eventually suffocating them. It treats the problem while respecting the scalp. Tip: you can apply coconut oil to damp hair and leave on for 10 to 30 minutes before rinsing again. You can also make a mask and leave it on overnight in a towel.

• A formidable natural insecticide, neem carrier oil is commonly used to treat skin infections such as fungal infections, eczema, psoriasis and acne. It is also an antibacterial and antifungal oil that is effective against lice and nymphs, and even inhibits the development of nits thanks to its azadirachtin content. As well as gently moisturising the scalp, it relieves the itching caused by these parasites biting the scalp. Its scent is powerful and plant-based, making it ideal for use in combination with coconut, tamanu or safflower oils, for example. Tip: as with coconut oil, apply it as a mask all over your hair and leave on for a few minutes or overnight before rinsing.

As a general rule, for both oils, we recommend leaving the oil mask on for 30 minutes to 1 hour, then shampooing your hair with an anti-lice shampoo containing essential oils.

Methodically combing wet hair with a lice comb is an effective alternative for combating lice and nits without using chemicals:

• Wash the hair, apply a small amount of conditioner to help immobilise the lice and make it easier to use a lice comb, then detangle the hair with a regular comb.

• Next, use a very fine lice comb, with less than 0.3 mm between the teeth, and comb the hair strand by strand, from root to tip.

• Wipe the comb on a white handkerchief or towel after each pass to check for lice or nits. 

• Rinse the hair thoroughly at the end of the procedure.

Repeat this combing process every 2 days for about 10 to 14 days. During an outbreak, you can use the comb on wet hair once a week for early detection, often even before the child starts scratching.

This natural, insecticide-free method is suitable for young children, pregnant women, and people with allergies. However, it requires time, patience, and great care. If done incorrectly or too infrequently, it may not be enough to completely eliminate lice, especially if the head is heavily infested or if those around the child are not treated at the same time.

Oily substances, such as organic coconut oil, organic neem oil, and petroleum jelly, can be used to block the respiratory openings of lice and eradicate them. However, this method is not very effective on nits, and must therefore always be followed by very thorough combing of hair that is still slightly oily or after rinsing. To do this:

• Apply the oil to dry hair, focusing on the scalp, neck, and behind the ears.

• Leave on for 30 minutes to several hours, or even overnight, depending on tolerance and the product.

• After application, comb through the hair with a fine-toothed lice comb, strand by strand, to remove dead or weakened lice and nits.

• Shampoo once or several times to remove the oil.

This procedure can be repeated 7 to 10 days later to combat any lice that may have hatched from the nits that survived, combing thoroughly after each treatment.

Vinegar, whether white or cider vinegar, is particularly useful for loosening nits and making them easier to remove with a comb. It does not directly kill lice. The acidity of the vinegar softens the glue that attaches the lice eggs to the hair. This technique can be used as a complementary step to anti-lice oil treatments made with coconut or neem oil. 

• Dilute 50% vinegar in 50% water.

• Heat the solution slightly for greater comfort, then dampen the hair.

• Dip a fine-toothed lice comb into the solution and comb through the hair strand by strand, starting at the top of the head and working toward the nape of the neck.

• Dip the comb back into the solution after each stroke to thoroughly saturate the hair and loosen the nits.

This procedure must be repeated after one week, then again one week later, to break the lice life cycle, with the vinegar helping to minimize the number of surviving nits.

Certain precautions must be taken when using essential oils to combat head lice:

• Never apply pure essential oils directly to the skin, especially to children, as this can cause irritation.

• Always dilute essential oils in a carrier oil before application.

• Perform a skin tolerance test on a small area of skin before use.

• Avoid contact with eyes and mucous membranes.

• Do not use essential oils on pregnant women, children under the age of 3, people with asthma or allergies without prior medical advice.

By following these precautions, essential oils can be used safely and effectively to prevent and treat head lice infestations.
