Head Lice Procedures

Please notify the school office if you find lice in your child’s hair. This will help to
contain the spread of lice in the school. Upon checking the student in school, it will be
necessary that a parent pick up a child immediately if any nits or lice are found. Re-admittance
from the health office will only be allowed after proper treatment is received
at home, all nits are removed and the health office staff conducts a head re-check.
We have a No-Nit policy, which means that a student is not allowed to return to school
until all nits are removed. Bus transportation will not be available until the child is re-admitted
through the school health office.

Description of Head Lice Infestation
Lice are blood-sucking insects which can inhabit the hair of the head. Lice are sensitive
to extreme temperature; they require normal body temperature to survive and they move
by crawling. The head louse lays its eggs (nits) on a strand of hair; nits are about 1/32” in
size, grayish-white, and have a glistening appearance if viable. Dead nits are dull and dry
in appearance. Head lice migrate from host to host through direct person to person
contact, or indirectly through bed linen, head gear, hair brushes, combs, hats, and coats.

Treatment is directed at the infested individual and his/her personal articles.

Individual Treatment
1. Remove all of the child’s clothing, place him/her in a bath or shower, and put the
clothing in a plastic bag.
2. Apply special medicated shampoo and wash the hair according to the label
directions. There are medicated liquids and gels available at any drug store for head lice. Some products are available by prescription only; others may be purchased without prescription. There is no published evidence that one product is superior to the others.
3. Rinse the hair with a warm vinegar solution to loosen nits.
4. Comb hair with a fine-tooth comb to remove any remaining nits.
5. Have your child put on clean clothing after the treatment.
6. If hair is long and thick, it will take longer to remove all nits and may require another
application of shampoo in 24 hours. Do not exceed recommended dose of application.
7. Check all family members, and if they show evidence of infestation they also should
be treated.
8. Repeat treatment in 7 to 10 days. While the medicated liquids rapidly kill crawling
lice, they may not kill all the nits. Therefore, the treatment should be repeated in 7 to 10
days to kill newly hatched lice. The 7 to 10 day interval corresponds to the incubation
period of a louse’s egg.
