Head lice are tiny parasitic insects that live in the hair and on the scalp of humans. The head lice feed off of the blood which causes small bites that can itch. The movement of the lice on the head can also cause itching. They lay eggs and reproduce quickly if they are not treated. They can spread from one human to another through head to head contact or through transfers on combs, brushes, hats, pillows, blankets, furniture or clothing. There is a common misconception that those who get lice are dirty or have poor personal hygiene. This is not true, in fact lice actually prefer clean hair.http://www.mayoclinic.com/health/head-lice/DS00953
Signs of Head Lice
The main signs of head lice are seeing the lice or nits on the head and hair. The nits will be glued to the hair and may be hard to spot if you are not in a well lit area. The lice may scurry to get out of the light when you are inspecting the head. Other signs of head lice can include itching and a red rash, small bumps or sores due to scratching.http://kidshealth.org/parent/infections/common/lice.html
Head Lice Treatments
There are over-the-counter shampoos and creams available to help kill the head lice. There are also prescription shampoos that may be prescribed by a physician. These shampoos kill the lice but the nits will still be attached to the hair. In order to remove all the nits, you can purchase a special comb for removing them or use a very fine toothed comb to loosen and remove them. The hair will need to be gone over thoroughly and it may take a couple of times before you can be sure that all the nits have been successfully removed. This will need to be done for everyone living in the household.
All clothing, bedding, stuffed animals and any other washable items need to be washed using the hot water cycle and then dried for a minimum of 20 minutes in the dryer. Any items that can not be laundered should be sealed in plastic bags for at least 2 weeks. Vacuum the carpet and furniture thoroughly.http://www.dhpe.org/infect/lice.html
