Treatment for Head Lice Infestation
Treatment options for head lice infestation typically involve the use of over-the-counter or prescription medications designed to kill lice and their eggs. These treatments may come in the form of shampoos, creams, or lotions. In addition to using medicated products, combing the hair with a fine-toothed comb can help remove lice and nits.
It is important to follow the instructions carefully and repeat the treatment as needed to ensure all lice are eliminated. In some cases, home remedies or natural treatments may also be effective in managing head lice infestations.
- Overthecounter (OTC) medicated shampoos: These shampoos contain insecticides that kill head lice and their eggs.

- Manual removal with a finetooth comb: Combing through the hair with a finetooth comb can help remove lice and nits (lice eggs) effectively.
- Home remedies such as oil treatments: Applying oil (like olive oil or coconut oil) to the hair can suffocate lice, making it easier to comb them out.
