Head lice are tiny insects that lay eggs, or nits, that stick to hair very close to the scalp.
The nits are grayish white and oval-shaped. Linda Patterson, health education associate specialist with Mississippi State University's Extension Service, said lice are easily transferred, and early detection should improve control efforts. Head lice are very common in groups, especially children. Sharing combs, brushes, hair decorations, headphones, helmets, pillows, stuffed animals and towels can easily transmit lice from one person to another. Patterson suggested regularly cleaning brushes and combs in hot water to reduce the risk of transferring lice.
