Full Answer

Head lice usually attach on the human scalp and feed on blood from their host. It is difficult to see these insects since they avoid light and hide under human hair. However, closely examining the hair on the head of a person suspected to have the insects may reveal the insects, especially if they have multiplied in number.

Another way to know whether a person's hair may be infested is by observing whether they display symptoms of itchiness around the ears, head and neck. It is these parts of the body that the insects bite when sucking blood from the host, which causes the affected individual to experience an itchy sensation.

Close observation of the hair may also reveal nits or eggs attached to the shafts or strands of hair. School-going children and their caregivers are at the greatest risk of infestation, according to Medicine Net.
