I know that there has been lice going around school-my neighbor and her daughter just had it too and today my dd(7) came home from school and is itching her head over and over.I have been checking her everyday for the last 2 weeks and have not seen anything and I checked her today and still I don't see any nits or bugs.She has very long medium brown hair and I know it can be hard to see but I keep looking.I don't know if she has it or not or what I should do.Anyone had it present like this first-itching but no sign of lice.Any recommendations as what to do next?
