Head lice infect the scalp hair and are easiest to see at the nape of the neck and over the ears.
They appear much like flakes of dandruff , but are stuck firmly to the hair shaft instead of flaking off of the scalp. Risk factors include close, overcrowded living conditions, and poor hygiene. Lice spread readily among school children. It is important to note that having lice is not an indicator of poor hygiene or low socioeconomic status.
