We did the whole RID Lice treatment. And she had 3 shampoos yesterday! I hope her hair doesn't fall out.
After much intense, academic, through internet research we don't think it is Lice after all. We didn't find any nits or other lice after all the cleanings and combings. And looking at a lot of gross photos online the bug we saw was black and round. Not white or reddish brown and oval.
We are keeping a vigilant eye but I think we are in the clear. However, there was a bug in her hair. And we've had the exterminator to our house 3 times! How can any bug still be alive in there?
