Question: how long does it take for lice bites to go away?
Answer: It may take a few days for the itching to stop, and the treatment may need to be repeated in 7 to 10 days to make sure any surviving lice are killed before they produce new eggs. Sometimes, adults choose to skip the medicated shampoo and only use a fine-toothed comb to remove the lice and nits from the hair.
