Some people use coconut oil in the hair to serve as a repellent against lice in an effort to prevent infestation or reinfestation but there is no research data to indicate that this is effective. Hair Combing Combing the hair to remove nits and lice that survived the shampoo treatment is the key to successfully controlling this pest. This process is time consuming but critical for success. If you do not completely remove all nits, reinfestation will most likely occur. This process should be repeated daily as long as nits and lice are still found on the head.
Many people use nit combs to remove nits from the hair shaft.
Metal lice combs can be found at drug stores or ordered from the National Pediculosis Association, Inc., listed in References, which has a specially designed nit comb called the LiceMeister TM . The hair can also be cut out with small safety scissors. The person to be treated should be seated near a good light source. Leave the shampoo in and towel dry the hair. Then comb the hair using a regular comb to remove snarls and the accumulation of soap suds.
