<human>:  What is the best way to prevent getting head lice?
<bot>: The best way to prevent getting head lice is to avoid close or prolonged head-to-head contact with someone who has head lice. It is also important to not share items such as combs, brushes, hair ties, hats, or other items that touch the head of a person with head lice. Regularly washing bed linen and clothing that may have been touched by a person with head lice can also help to prevent catching head lice.
