Natural remedies are sometimes touted for treatment of head lice, a type of parasitic insect that lives on the scalp and feeds on its host's blood. Spread by close contact with other people, head lice are especially common among school children. Although head lice can cause severe itching, they do not carry diseases or contribute to major medical problems.

Standard treatment for head lice infestation involves the use of an over-the-counter shampoo containing 1% permethrin (a synthetic insecticide).

However, certain natural remedies may also help get rid of head lice.

Natural Treatments for Head Lice

Preliminary research suggests that certain natural remedies may help eliminate head lice. Here's a look at some key study findings:

1) Head Lice and Essential Oils

A number of essential oils hold promise in the treatment of head lice infestation. For instance, laboratory experiments indicate that tea tree, peppermint, cinnamon leaf, lavender, and eucalyptus oils can destroy head lice. However, it's important to note that what happens in a test tube may not occur when essential oils are applied to the scalp.

To date, few clinical trials have tested the effectiveness of essential oils in treatment of head lice. The available human-based research includes a 2010 study from BMC Dermatology, which involved 123 people with head lice. Study results revealed that a topically applied product containing tea tree oil and lavender oil was more effective against head lice than a product containing pyrethrins and piperonyl butoxide (two substances found in a shampoo commonly used to treat head lice).

2) Head Lice and Neem

Several small studies show that shampoos containing neem extract may help get rid of head lice. Widely used in ayurvedic medicine, neem extract has insecticidal compounds called azadirachtins.

In a 2011 study published in Parasitology Research, for example, scientists used a neem-extract-based shampoo on 12 children with head lice.

They found that a one-time, ten-minute treatment with the shampoo destroyed all head lice. Repeating the experiment with eight other children, the study's authors found that a one-time, 20-minute treatment delivered the same results. Other research shows that neem-extract-based shampoo may get rid of head lice and their eggs without triggering any side effects.


Due to a lack of research, little is known about the safety of essential oils and neem. Essential oils should not be applied at full-strength to skin or scalp. Essential oils are absorbed through skin -- excessive amounts can cause overdose and have adverse effects. 

It's important to keep in mind that supplements haven't been tested for safety and dietary supplements are largely unregulated. In some cases, the product may deliver doses that differ from the specified amount for each herb. In other cases, the product may be contaminated with other substances such as metals. 

Also, the safety of supplements and essential oils in pregnant women, nursing mothers, children, and those with medical conditions or who are taking medications has not been established.

Using Natural Remedies for Head Lice

If you experience symptoms of head lice, it's important to seek treatment as soon as possible. Head lice symptoms include intense itching of the scalp; small red, bumps on the scalp, neck, and shoulders; and tiny, white, hard-to-remove specks (eggs) on the end of each hair. The National Institutes of Health recommend pursuing treatment even if you only find one egg. While head lice infestation typically doesn't lead to serious medical issues, secondary skin infections can result from scratching.

Due to the limited research, it's too soon to recommend essential oils or neem as a treatment for head lice. If you're considering the use of natural remedies to eliminate head lice, talk to your doctor first. Self-treating and avoiding or delaying standard care can have serious consequences.
