Shampoo and comb!: A thorough shampoo with l% Permethrin (nix) is the most effective over-the-counter treatment. This should kill all the live insects. Then it is very important to use a fine-tooth comb through the hair and remove all the tiny white eggs (nits). These may hatch later if not removed, and start the problem all over. There are also stronger prescription drugs that your dr. May recommend.

Lice not Nice.: Tx of lice requires accurate identification of nits & lice. A pediculicide is usually used- OTC like Nix or RID or prescription meds like lindane or malathion. Work carefully through hair & remove individual nits. Purchase a special lice nit comb to aid you. Check for nits & remove as seen over the next 7 to 10 days. If there are nits after 7 to 10 days – a 2nd pediculicide tx may be needed.

Remedies: Natural remedies for lice include the application of olive oil, mineral oil or mayonnaise to the head/ hair. These oil-based products smother the louse. However, there is no research to demonstrate treatment efficacy.

Wash clothing or linens in HOT Water. Soak personal items like combs or brushes in HOT water for at least 10 minutes (or throw them out if this is an option). Vacuum floors, carpets, mattresses, upholstered furniture & your vehicles.

New activity: You can be infested with juvenile lice before they start laying eggs & not recognize the activity.If you have removed the egg casings & killed the lice, you must wait out the next 2 weeks to see if you have got them all.Any that were missed or hatching new would take up to 10 days to mature & lay recognizable eggs.
