Can a Hair Relaxer Kill Lice?

This article will go over the ingredients in many popular hair relaxers that can help you kill lice and prevent them from infesting your home. Some of these ingredients are Tea tree oil, Dimethicone, Piperonyl butoxide with pyrethrins, and Ulesfia. But before you try any of them, make sure you do your research and use them appropriately. They may kill the lice in your home, but there’s no guarantee that they will.

Tea tree oil

Using Tea tree oil as a hair relaxer is a safe and effective way to kill lice, and it also soothes irritated scalps. It deep cleans hair and follicles. The oil can be applied liberally to the hair, both lengths and roots. It is a natural product that will clean your hair without the use of shampoo. You can even use it to fumigate your drawers.

Tea tree oil has proven natural pesticides, so it can kill lice. It has also been known to inhibit the re-infestation of hair. It is an excellent natural product to use to wash and condition your hair, and its anti-fungal, antibacterial, and antiseptic properties help protect against hair-infesting bacteria. Its anti-inflammatory properties make it a popular choice for aromatherapy and can also support the immune system.


A popular dimethicone-based head lice product is NYDA express, which requires only one application, and takes ten minutes to kill head lice. Although dimethicone kills head lice at all stages of their life cycles, this product is not effective if the lice develop resistance. The chemical leaves a residue in the hair, which the lice cannot easily remove. Moreover, dimethicone is not neurotoxic and does not have a strong chemical smell, which makes it suitable for all age groups.

The active ingredient dimethicone is a nonvolatile liquid gel that coats louse eggs thoroughly. Liquid gels also have a nonvolatile vehicle such as polyethylene glycol/polypropylene glycol dimeticone co-polymer and a silica silylate thickener to enhance the adhesion of dimeticone to hair. However, some components of the liquid gel cannot be removed with the shampoo.

Piperonyl butoxide with pyrethrins

Using pyrethrin and piperonyl butoxide shampoo can kill lice and prevent them from returning. However, you must always be sure to wash your hair and body with water afterwards. Do not apply it to your eyebrows, eyelashes, or skin. Always wash them off thoroughly. Mix the shampoo well before using it. Follow the instructions carefully and don’t use more than what is recommended.

Piperonyl butoxide and pyrethins are two of the main ingredients in most over-the-counter lice medications. Pyrethrins are derived from the flowers of the ragweed plant. They work together by inhibiting the lice’s metabolism and enhancing their effects. This combination may also reduce the development of resistance to pyrethrins. Pyrethrins and piperonyl butoxide are approved by the FDA for use in the treatment of Pediculus capitis and Pediculus corporis in children and adults.


A good way to kill lice is to apply a hair relaxer. Once applied, leave it on for 30 minutes. Then wash and dry your hair with a hand dryer. If you still have lice, wash your personal items in boiling water. You can also use a hot comb to kill lice. You need to repeat this process several times to ensure that every last one has been removed. If this method does not work, you may need to contact your doctor.

Using the right medication to kill lice is crucial. Never use flammable products on your head. If you’ve used a product more than three times, see a doctor. If your head lice treatment has failed, try another. You’ll need to wash brushes, hats, and pillows in hot water, too. Once they’re clean, you need to put them in an airtight plastic bag and wait for a few days.

Tea tree oil with pyrethrins

Although pyrethrins are relatively safe for humans, they are still harmful for pets and children. Animals exposed to these chemicals may develop cancer if they breathe the fumes in, or they may become irritated or burnt. Exposure to high concentrations can also cause liver changes, such as tumors. Luckily, the Environmental Protection Agency (EPA) has classified these chemicals as non-carcinogenic, but there are still some precautions that should be followed when using this type of insecticide.

The efficacy of tea tree oil and nerolidol against Pediculus capitis was assessed using strict criteria. For example, if no external or internal vital signs were observed in treated eggs, the lice were dead. Combined treatments of tea tree oil and nerolidol were more effective in killing live lice. The two treatments killed lice in a single treatment, and they had comparable efficacy against nymphs.

Ulesfia with pyrethrins

Pyrethrins are a natural insecticide derived from the chrysanthemum flower. They are neurotoxic to lice and have low mammalian toxicity. Pyrethrin-based lice shampoos are applied to the scalp and hair. These products work by coating the louse with an oily film that prevents them from excreting water. The oil also ruptures the louse’s guts, killing them.

To apply the lotion to the scalp, you need to cover your head with a towel and leave it on for 10 minutes. Then, rinse it out carefully. Do not forget to rinse your hair after each treatment. However, you cannot kill the eggs with this product. You should continue the treatment for seven days after the initial application. To prevent future lice infestations, you should use the product at least seven days after you have finished the first treatment.
