How can I tell if I've got headlice or just dandruff? I think I've seen a couple of headlice in my daughters hair. Tiny little black things plus some white bits that could be the nits or possibly dandruff as she also gets that bad sometimes. I also get bad flaky scalp. I've used the headlice stuff and been regularly combing. I've found a few in my daughters hair but not alot. I dry combed mine and there seemed alot of white stuff how do I know if its just dandruff or not? Some bits were quite big. I can't ask anyone to do it for me either. So far I haven't seen any black bugs in the comb or on the toilet roll.
