Has anyone experience with their kids with ich and head lice. I got head lice from somewhere (no idea where) but cannot see it in my girls, but then apparently the lice eggs are white and I don't think I can distinguish between the eggs and scales perhaps?

Should I just treat their heads to be safe (already did it once but for less than recommended time)? And they don't seem to be scratching. And so far I have not seen any lice.
I have two daughters, both with nbCIE.
