One thing is certain, to have lice and nits on your head is not very pleasant. But that’s not why you have to spend tons of money to get rid of it. Why? Because there is a natural and cheap remedy to do it. Head lice are tiny insects that feed on the blood of the scalp. Children are often the most affected, especially girls, with their long hair. One in ten children is affected by lice at some point in their schooling because the transmission of the head to head lice is very easy. To treat lice that your child has caught, no need to buy an anti-lice shampoo.

According to Scalp Conditions:

Several things can cause itching, flaky, uncomfortable scalps: an allergic reaction to a hair care product, dry skin, unwashed hair, shampoo residues, sticky conditioners, an accumulation of sweat and oil, an increase in the number of fungi or bacteria on the surface, exposure to extreme temperatures or simply not washing your hair enough. Just like the skin on the rest of the body, the scalp requires routine cleaning and adequate stimulation to stay healthy. However, scalp problems occasionally also occur with proper care. Although they are not life-threatening, they are unsightly and can cause self-consciousness and personal discomfort.

How does it work?

Before becoming a popular mouthwash, Listerine was used to disinfect wounds. The combination of alcohol, benzoic acid, menthol, methyl salicylate, and thymol kills germs, bacteria, and fungi on contact, effectively eliminating the dandruff-causing microorganisms. In addition, Listerine has astringent properties that tighten the pores, reducing the amount of oil on the scalp. It also contains essential oils that relieve itching when removing dirt, grime, and styling residual products.


Listerine is an alcohol-based compound and should therefore not be applied to open wounds or with chapped skin as this will cause an extremely uncomfortable burning sensation. While Listerine is available in a wide range of flavors and formulas, original brown is probably the best choice for medicinal purposes as it contains less artificial and flavoring colors.
