I'm not sure if its white but maybe not. The thing is, when i went to scratch my hair, some small white stuffs with holes came out. Not too much After scratching for about 10 seconds. They had like 20 of those in the black paper. Is it poo. I hope not...
Those with headlice aren't allowed to go to school.
Yeah, I learned that the hard way. had to wash my hair with this shampoo stuff for like 3 times a day for like 3 days to kill them all. Was annoying, my mom wouldn't let me sit on the furniture. XD
But yes, it does sound like lice. Dandrufed is just small white flakes, not round or with holes in it. Sides, dandruff is from a dry scalp...not much to worry about there, though some say it may lead to hair lose....
It can possibly be dandruff, lice, lice eggs or just dust. For dandruff use a special shampoo, or some people said dunk your head in a bowl of cold water everyday. Your scalp could be too dry.
For the rest...I'm not sure, better ask the doctor. If it's moving, immediately go!
Fun fact : Some ancient monks use large combs to try and root out lice. One was even buried with an ivory comb.
