Head lice are tiny insects that are light grey to brown in color.
The nits are tear-shaped and unlike dandruff, they adhere tightly to the hair shaft and are note easily removed. They are not caused by lack of cleanliness. Head lice are easily spread from person to person usually by close head to head contact and by sharing personal items such as scarves, hats and combs. Animals do not transmit head lice. Effective control of head lice requires adequate treatment of the infested individual, household and other contacts, personal articles, and home environment.
