Lice infestation: Is camphor and chemicals enough?
As lice infestations become a growing talking point again, here is what health experts say about the effectiveness of camphor, harsh chemicals and the treatments that actually work.
Just when many people thought head lice had become a thing of the past, cases are once again becoming a common talking point. Across homes, workplaces, salons and social media, more people are sharing experiences of dealing with persistent lice infestation, with adults finding themselves just as affected as children. The renewed conversations have also revived old remedies, with camphor and a variety of strong chemicals often mentioned as the quickest way to get rid of the tiny parasites.
The problem is that not every popular remedy is an effective one. While some methods have been passed down for generations, others have gained traction through word of mouth and social media without any scientific backing. In some cases, these treatments may not only fail to eliminate lice completely but could also cause unnecessary harm to the scalp and overall health.
Head lice are tiny parasitic insects that feed on human blood and spread mainly through close head-to-head contact. Contrary to a common misconception, they are not a sign of poor hygiene and can affect anyone, regardless of age, hair type or social status. According to the World Health Organisation (WHO), head lice remain one of the most common parasitic infestations globally, particularly in communities where close contact is common. With conversations about lice infestation becoming more frequent again, understanding what actually works has never been more important.
Why camphor and harsh chemicals are not the solution
For decades, camphor has been one of the most popular home remedies for head lice infestation in many Nigerian households. Some people keep it under their pillows, while others crush it into hair cream or shampoo, believing its strong smell will either kill the lice or force them out. Although camphor may have insect-repellent properties, there is no credible scientific evidence that it can completely eliminate head lice or destroy their eggs, also known as nits.
The same applies to many of the harsh chemicals people turn to out of frustration. From insecticides to kerosene and other toxic substances, these products are sometimes used in the hope of getting faster results. However, health experts strongly advise against such practices. The United States Centers for Disease Control and Prevention (CDC) warns that applying these substances to the scalp can cause chemical burns, skin irritation, breathing problems and even poisoning, particularly in children.
Even some medicated lice treatments are not always as effective as they once were. Researchers have found that head lice in several parts of the world have developed resistance to certain insecticides, including permethrin and pyrethrins, which have long been used in lice treatments. This means that using stronger chemicals or combining multiple products is unlikely to solve the problem and may instead increase the risk of damaging the scalp.
What actually works?
Getting rid of lice requires patience more than anything else. Health professionals recommend using products that have been specifically formulated to treat head lice and following the instructions exactly as directed. If the infestation persists after treatment, it is advisable to speak with a pharmacist or healthcare professional, who may recommend an alternative treatment.

One of the most effective ways to remove lice is still one of the simplest. Using a fine-toothed lice comb on wet hair helps remove both live lice and their eggs. Because not every egg hatches at the same time, the process should be repeated over several days to prevent the infestation from returning.
It is equally important to deal with items that may have come into contact with the hair. Pillowcases, bed linen, towels, hats and recently worn clothing should be washed and dried properly. Hairbrushes and combs should also be cleaned thoroughly before they are used again. However, there is no need to spray the entire house with pesticides or disinfectants. Head lice cannot survive for more than one or two days away from the human scalp, making extensive household fumigation unnecessary.
Another common myth is that pets spread head lice. They do not. Human head lice survive only on humans, so there is no need to treat household animals. It is, however, sensible to check people who have had close head-to-head contact with the affected person, as lice can spread easily among family members, partners and friends.
Although discovering lice can be frustrating and embarrassing, there is no reason to panic. The lice infestation has nothing to do with personal cleanliness, and it can happen to anyone. Rather than relying on remedies that have been passed down without scientific proof, choosing evidence-based treatments is the safest and most effective way to get rid of lice and prevent them from coming back.
The next time someone recommends camphor or a harsh chemical as a guaranteed cure, remember that the strongest remedy is not always the best one. When it comes to treating head lice, proven methods backed by medical evidence will always outperform myths and quick fixes.
