Alternative Method Description
Manual Removal Using a fine-toothed comb, meticulously remove all visible nits and lice from the hair, paying close attention to the nape of the neck and behind the ears. Repeat this process daily for at least two weeks, or until no more lice or nits are found.
Essential Oils Certain essential oils, such as tea tree oil, lavender oil, and rosemary oil, have shown potential in repelling and killing lice. Dilute these oils with a carrier oil, such as coconut or olive oil, and apply to the scalp and hair. Leave the mixture on for at least 30 minutes before rinsing thoroughly.
Olive Oil Suffocation Coat the hair and scalp liberally with olive oil, ensuring full coverage. Leave the oil on overnight, covering the head with a shower cap or plastic wrap. In the morning, wash the hair thoroughly with a lice shampoo or regular shampoo.
Vinegar Rinse Mix equal parts white vinegar and water in a spray bottle. Spray the solution onto the hair and scalp, ensuring it reaches the roots. Leave it on for at least 30 minutes before rinsing thoroughly with water. The acidic nature of vinegar helps to dissolve the glue that attaches nits to the hair shaft.
Heat Treatment Using a hair dryer or a lice comb that emits heat, expose the lice and nits to high temperatures. Heat can effectively kill both lice and nits. Be cautious to avoid causing burns or scalp damage.
