head lice
"My oldest daughter had tons of live lice and eggs while my youngest appeared to only have eggs. We tried OTC and googled remedies without success. Went to the pediatrician and she Rx sklice which seems like it worked at first but now three weeks later there's STILL eggs visible on my oldest daughter's hair. Youngest is clear. I've been combing out eggs daily up to twice a day and STILL she has eggs. Frustrating"
