Did you know that head lice infestations affect an estimated 6-12 million children in the United States each year? While there are many treatments available to eliminate lice and their eggs, some people turn to hydrogen peroxide as a natural alternative.
One such remedy is hydrogen peroxide, which is believed to be effective at killing lice and their eggs.
Hydrogen peroxide is a naturally occurring substance that has antiseptic and antibacterial properties. When applied to the scalp and hair, it can penetrate the exoskeleton of the lice and damage their internal organs, ultimately killing them.
Let’s take a closer look at the research and see if you should try it!
Can Hydrogen Peroxide Be Used to Kill Lice?
Hydrogen peroxide can be used to kill lice, but it is not the most effective or recommended method for lice treatment. While it is a common household disinfectant that can kill bacteria, viruses, and other microorganisms, it is not specifically designed to target lice and their eggs.
Using hydrogen peroxide for lice treatment requires diluting it with water to reduce its concentration and applying it to the scalp and hair for about 30 minutes before combing out the dead lice and nits using a fine-toothed comb.
However, hydrogen peroxide may cause skin irritation, so it should not be left on the scalp for too long.
Other treatments such as prescription medications or over-the-counter lice shampoos are more effective and have been extensively tested for safety and efficacy.
These products have been specifically designed to target lice and their eggs and can eliminate the infestation more thoroughly than hydrogen peroxide.
It’s important to consult with a healthcare professional or a licensed pharmacist if you suspect that you or someone in your household has lice. They can recommend the most appropriate treatment based on the severity of the infestation and any individual factors, such as age or underlying health conditions.
The Effectiveness of Hydrogen Peroxide for Head Lice
Head lice infestations can be a frustrating and persistent problem, especially in households with children.
While there are several over-the-counter and prescription treatments available, some people may consider using household disinfectants such as hydrogen peroxide as an alternative treatment option.
Hydrogen peroxide can be effective in killing lice, but it is not as effective as other treatments such as prescription medications or over-the-counter lice shampoos. These products have been specifically designed to target lice and their eggs and have been extensively tested for safety and efficacy.
What Does Hydrogen Peroxide Do To Lice?
When hydrogen peroxide comes into contact with lice, it releases oxygen, which can suffocate and kill the lice.
Lice are small, parasitic insects that feed on blood and live on the scalp and hair. They can cause itching and irritation and are most commonly found in children. Lice infestations are spread through close contact with an infected person or through sharing personal items such as combs, brushes, or hats.
Hydrogen peroxide works by breaking down into water and oxygen when it comes into contact with organic matter, such as lice or their eggs (nits).
The oxygen released from hydrogen peroxide creates a foaming action that can help to remove debris and dead lice and nits from the scalp and hair.
The oxygen bubbles can also suffocate lice and their eggs by blocking their airways. Lice breathe through small tubes called tracheae, which are located on the surface of their bodies.
When the oxygen bubbles from the hydrogen peroxide come into contact with the lice, they can block the tracheae and suffocate the lice.
It’s important to note that while hydrogen peroxide can be effective in killing lice, it is not the most effective or recommended method for lice treatment.
What Does The Research Say?
According to a study published in the Journal of Pediatric Nursing, hydrogen peroxide was found to be less effective in killing lice and nits compared to over-the-counter lice treatments.
The study involved 148 children with head lice infestations, and the results showed that hydrogen peroxide was only effective in 25% of cases compared to 97% effectiveness with a lice shampoo containing permethrin.
Another study published in the Journal of Medical Entomology found that hydrogen peroxide was effective in killing lice and their eggs but required a longer exposure time and a higher concentration than over-the-counter lice treatments.
However, a study including 80 children with head lice infestation showed better outcomes. They divided the kids into two groups, with one group treated with HP and the other with malathion lotion.
Both treatments were effective in killing lice and their eggs, but malathion lotion had a slightly higher success rate (94.7%) compared to HP (87.5%).
However, the difference in effectiveness between the two treatments was not statistically significant. The study also found that HP had fewer side effects compared to malathion lotion.
The study concludes that 1% hydrogen peroxide can be considered an effective and safe alternative to malathion lotion for the treatment of head lice infestations in children.
How to Use Hydrogen Peroxide to Get Rid Of Lice?
Head lice infestations can be a frustrating and uncomfortable experience, and many people seek natural or alternative treatments to avoid using harsh chemicals on their scalps.
Hydrogen peroxide is one such option that is commonly used for treating head lice. While hydrogen peroxide has been shown to be effective in killing lice and their eggs, it is important to use it correctly to avoid any potential side effects or damage to the scalp.
#1 Using Hydrogen Peroxide Shampoo to Kill Lice
Hydrogen peroxide shampoo is a specially formulated shampoo that contains hydrogen peroxide, an antiseptic agent that is commonly used to clean and disinfect wounds.
When used to treat lice infestations, the shampoo is applied to the hair and scalp and left on for a period of time, usually between 10 to 15 minutes. The hydrogen peroxide in the shampoo is believed to kill lice by breaking down their exoskeletons and dehydrating them.
