With head lice, the parasite is on the scalp attached to hair stands. Bites or pustules may be observed behind the ears and at the hairline. Grayish-white parasites with red legs are pediculosis pubis (crab lice), not head lice, and are found in pubic hair. Alopecia (hair loss) is found in all races, with brittle and broken hair and balding patchiness in the periphery of the hairline.
