I will keep my fingers crossed for you Lenore.
HeadLice.Org For Kids - Hair Force One
Something funny I found.
I saw a big boss louse on my hair today, turned out it was beetle and I squished it between my fingers which was not a good idea as the top of my hair was covered in brown bits everywhere. I am getting paranoid now and seeing them everywhere! ARGGHHHHH!!!
As for the school... well they sent letters out but they got rid of their no nit policy as too many kids were missing school, I kept my two at home and treated them but some people just send their kids in and all they have to do is sign they treated them, don't need a letter from the doctor or anything saying they are clear so it keeps spreading... Really annoying and itchy!
