If I scratch my head, the itching sensation is INTENSE, and I try never to scratch my
scalp. If I
do give in, and scrape a few dozen of them off, I can
get them out form under my fingernails (gross, I know), and they look like grains of sugar or sand. They are hard like grains of sand. You can not "squish" them.
They are not lice...my husband is an RN, and he has looked at my scalp many times, and we are certain of this.
