ive only shared a pillow with maybe one person that has shared with others and well, my head is soooo itchy. well, not so itchy..doh. but it doesnt go away really. i read that certain shampoos can do that and i use strong shampoo... also it's cold. i dont have dandruff.. cause when i itch, no flakes. could it just itch cause it's cold? i really only had ONE oppurtunity in 8 months to get lice but the lice thread has me worried. if it's just cause it's dry (which i suspect)- how do i fix it? and how do i find out if that's not it?
