Ingredients Found In Head Lice Shampoos

Head lice shampoo can help prevent future infestations by killing lice on the head. These pesticide-resistant bugs are often resistant to the pesticide permethrin. These pesticides are often used to kill lice, but the problem is that these pesticides can pollute waterways and kill bees. Fortunately, there are other alternatives to permethrin, such as dimeticon. Before you buy head lice shampoo, it’s important to learn about its ingredients. Here is complete info about lice shampoo ingredients.


Permethrin is a synthetic pyrethroid. It is used in head lice shampoo and creams. The lotions contain a 1% concentration of permethrin and are approved by the FDA. These products kill live lice but not their eggs. However, they may continue to kill newly hatched lice days after applying the lotion. Therefore, a second treatment is often needed after the first.


Pyrethrin is a common component of head lice shampoo. But you should be careful about this chemical, which has a history of causing allergic reactions. The chemical, a pyrethroid, is a natural substance in chrysanthemum flowers. It is a possible allergen for some people, and children’s skin is sensitive to it. You should never use this ingredient on your children, as they may experience a negative reaction.

There are several ways to avoid this common ingredient. First, avoid using it on your eyes. It can be harmful if it gets in your eyes, so rinse it thoroughly with water. Second, avoid getting the medication on your clothing. This is because the lice may become resistant to it, making it ineffective.


The main ingredient in head lice shampoo is malathion, which blocks the activity of a protein in lice. This kills off live lice and eggs. You should use malathion shampoo every three to four days, washing your hair after each treatment.

This ingredient is generally safe for adults and children, but you should consult your doctor before using it. You should also avoid using it on young children or anyone who may be allergic to malathion. It is also important to follow the directions on the packaging and keep the shampoo out of reach of children. You should also store it in a cool, dry place away from direct heat and light.

Benzyl alcohol:

Alcohol can be used as a treatment for head lice. When applied to the affected area, alcohol kills the lice on contact. The type of alcohol used will determine the effectiveness of the treatment. While it is effective, this ingredient also has some unwanted side effects.
