Everytime I scratch my head I get this weird white thing under my nails but anyways I rinsed my hair with this thing --->http://www.celestialseasonings.com/products/herbal-teas/cinnamon-apple-spice sunday and it was fine, I had some white things near my scalp but my mom checked and said it wasn't lice. Yesterday I rinsed my hair with a blended apples and some water and I woke up today with residue in my hair I mean it was so bad some of my hair strands where white like if you moved your hair when you had gel and it turned white. The residue came off when I pulled it off the hair and it wasn't just near the scalp it was all over the length. So I washed it with a sulfate shampoo and it got most of the gunk out but still, it still has some left and it's also near the scalp. So is it residue from the apple thing or dandruff or lice(I had lice when I was 9 and I wasn't itchy but boy did I have it) I really can't have lice since My hair is all the way to my butt crack and it's thick and curly. :(
I have no idea about the apple thing, no clue how that will end up dried in hair but it does sound like dead skin on your scalp which can build up if you don't wash your scalp or hair well enough.
I'm not sure what it is but it's not lice. Lice is little eggs on single strands of hair and you have to pull them off individually. I have psoriasis on my scalp, look it up maybe it could be that.
sounds like you have dandruff use head and shoulders it works really good
