What are head lice?
Head lice are small, parasitic insects that thrive by feeding on human blood. They are transmitted via hair-to-hair direct contact. Although the scalp is the most common site of infestations, other hair-bearing areas may be involved, including the pubic region, eyebrows, or eyelashes. Lice are particularly common among pre-school and elementary school-aged children, as they are are often picked up unknowingly while children play and socialize. Although lice do not transmit any diseases, they are highly contagious and can affect anyone — even if they are clean and healthy.
