Which over-the-counter remedy is most appropriate to treat head lice itching?

• A. Sulfur ointment
• B. Wet combing
• C. Permethrin Lotion
• D. Tea Tree Oil

Answer: (B)

The key idea is that itching from head lice comes from the bites of the lice, so removing the lice themselves is the most effective way to relieve itching, especially with a safe, OTC method. Wet combing works by physically removing lice and nits from wet, conditioned hair using a fine-toothed comb. This mechanical approach reduces the parasite burden without using pesticides, making it safe for most people and helpful when there are concerns about chemical resistance or skin sensitivity. It’s important to repeat the combing regularly over 2–3 weeks to catch newly hatched lice, and to clean personal items and surroundings to prevent re-infestation. While chemical lice treatments can kill lice, they carry potential resistance and side effects; less-supported options like tea tree oil or sulfur ointment are not as reliable. Wet combing directly targets the cause of itching by removing the lice, making it the most appropriate OTC choice in this context.
