I'm at my wits end - we've done 4 treatments in as many weeks and they are still creeping in ds hair. Every time we've treated , we've treated the whole family, changed bed clothes , I've text his best friend parents to warn them he's had nits hoping they would do a thorough check. I told the school who sent out an e mail about nits in the school. What else can I do?! Praying you all have a miracle cure!
