Both my dds (primary age) went back to school this term completely clear headed. Dd2 came home with 2 lice within 48 hours. No eggs, no further evidence of anything nit-related. I condition/nitty gritty them both a couple of times a week.
Last night, 2 weeks after finding 2 lice, I found 2 more. Again, no eggs, nothing else. Is it just a case of her being in contact with an infested child, and a couple are wandering onto her head but I am managing to comb them out before they start laying/hatching/breeding?!
