Prepare the neem oil mixture: Mix pure neem oil with a carrier oil, such as coconut oil or olive oil, in a ratio of 1 part neem oil to 10 parts carrier oil. This dilution helps to prevent skin irritation. Apply the mixture to the scalp: Gently massage the neem oil mixture onto the scalp, ensuring that it covers the entire scalp and hair roots. Pay extra attention to the areas where lice and nits (lice eggs) are commonly found, such as the back of the neck and behind the ears. Cover the head: Put on a shower cap or wrap a towel around the head to keep the neem oil mixture in place and to prevent staining of fabrics. Leave it on overnight: Allow the neem oil mixture to stay on the scalp and hair overnight. This gives the oil enough time to suffocate the lice and disrupt their life cycle. Comb out the lice and nits: In the morning, use a fine-toothed lice comb to carefully comb through the hair, removing dead lice and nits. Start from the roots and comb all the way to the ends of the hair strands. Wipe the comb on a paper towel or rinse it in warm, soapy water after each stroke to prevent re-infestation. Shampoo and rinse: Wash the hair thoroughly with a mild shampoo to remove the neem oil and any remaining lice or nits. Repeat the treatment: To ensure complete eradication of lice, repeat the neem oil treatment and combing process every 5 to 7 days for a few weeks. This helps to target newly hatched lice that may have survived the initial treatment. Take preventive measures: To prevent re-infestation, wash bedding, clothing, and personal items that may have come into contact with lice in hot water and dry them on high heat. Vacuum upholstered furniture and car seats, and seal non-washable items in plastic bags for a few weeks. It's important to note that while neem oil can be an effective natural remedy for head lice, it may not eliminate all lice and nits with a single treatment. If the infestation persists or becomes severe, it is advisable to consult a healthcare professional or a licensed pharmacist for further guidance and treatment options.
