The holidays bring joy, traditions and lots of close encounters with friends and family. Any gathering of people is a potential field day for head lice. If someone arrives at a Christmas party with head lice, there is a chance that several others will leave with head lice. So how can you stay lice free this holiday season? Follow these helpful tips! Avoid head to head contact. While lice can't jump or fly, they are transferred through direct contact from one host to another.
