Ok I was checking out my two boys last night because they seem to shed alot (but my 5 year old has always shed taht much, and hes been to the vet). But I noticed that my younger one has like white things in his hair. I thought it kind of looked like either dandruff or dry skin. It's not moving so its not Lice, and it doesn't really look like lice. But I was wondering if this is normal, and what can i do about it?
