2  Properly called Pediculus humanus capitis, head lice are parasitic insects that are small, wingless, and grayish-tan.  Head lice only live in humans, and anyone can get them, even with good health habits and hair washing.  Head lice is very common.

3  Nits are head lice eggs. They are very small, about the size of a knot in thread, hard to see, and are often confused for dandruff or hair spray droplets.  Nits are laid by the adult female at the base of the hair shaft 1/4 th inch from the scalp.  They are oval and usually yellow to white.  Nits take about 1 week to hatch.

4  The nit hatches into a baby louse called a nymph.  It looks like an adult head louse, but is smaller.  Nymphs mature into adults about 7 days after hatching.  To live, the nymph must feed on blood.

5  They are about the size of a sesame seed, has six legs, and is tan to grayish-white.  Adult lice can vary in color depending on the person’s hair color.  Females, which are usually larger than males, lay eggs.  Adult lice can live up to 30 days.  If the louse falls off a person, it dies within 2 days.

6  Gray bugs in hair  Nits (white eggs) attached to hair follicles  Itchy scalp  Scalp rash

7  ANYONE who comes close contact (especially head to head contact) with someone who already has head lice is at greatest risk.  You might also be at risk if you share clothing (such as hats, scarves, coats) or other personal items (brushes or towels) that belong to an infested person.  Preschool, elementary-age children, girls, and women have higher risks.  Personal hygiene or cleanliness in the home or school has nothing to do with getting head lice.

8  Start with over the counter treatment as directed on dry hair. Ask a pharmacist questions if necessary.

9  This is the most important step in getting rid of head lice.  No lice treatment kills 100% of nits, so all nits must be removed to prevent them from hatching. If one nit is left, the head lice problem could continue.  Mixture of half vinegar and half rubbing alcohol applied to the hair can help to loosen the nits prior to combing. As you remove the nits, put them in alcohol.  Good light is necessity! Sunlight or fluorescent lights are best. Nits will be missed in regular light.  Metal nit combs work better than plastic ones. Combing out nits is not the same as combing hair with a regular comb. Divide hair into small sections to comb through carefully.

10  Lice may live up to 3 days and nits up to 3 weeks. To prevent infection, vacuum child’s mattress daily, soak combs and brushes for 1hr in a solution made from anti lice shampoo, and wash all bed linens and clothes in hot water and place in dryer.  Vacuum carpet, cloth furniture, and seats of cars. Throw bag away.  Place all stuffed animals or items with cloth in an airtight bag for 2 weeks.  If lice or nits are seen on the eyelashes, apply Vaseline to the eyelashes twice a day for one week. NO anti lice shampoo should be used near the eyes or eyelashes.

11  Cover head and hair with mineral oil for 30mins.  Wash hair with Dawn dish soap until mineral oil is removed.  Apply white vinegar to cover all scalp and hair for another 30mins. Protect eyes.  Rinse vinegar with warm water thoroughly and remove all nits under bright light.  Treatment can be repeated as needed.

12  Your child may return to school when ALL nits are removed.  Have your child checked by a school nurse to make sure.  Retreatment is recommended in 7 to 10 days to remove any remaining nits or lice.  Check the heads of other family members.  If anyone has scalp sores, rashes or itching, they should be treated with the shampoo also.

13  Call your doctor if: - Itching prevents sleep - The scalp rash clears, then returns - The scalp rash lasts more than one week. - Living lice or eggs appear in the hair after treatment. - The sores spread or look infected. - Your child displays signs of infection such as increased swelling, redness, pain, drainage, bad smell from sores, and fever.

14  Hair spray or any other medicated sprays will NOT prevent head lice.  Head lice are mainly spread by head to head contact.  Head lice can also be spread indirectly…  Teach your child not to share combs, brushes, coats or hats!

15  If you have any questions, contact your school nurse.  You can also contact the following if you need help treating head lice or if you have questions: - Lice Ladies of Atlanta ( ) - Family Lice Removal ( ) - Natural Head Lice Removal ( )
