Frequently Asked Questions
Treatment and prevention FAQs
How can I prevent my child from getting head lice?
Head lice can be passed from one child to another, usually by head-to-head contact. The best way to prevent your child from getting head lice is to avoid sharing combs, brushes, barrettes, hair ribbons, headbands, or other personal items such as hats, sweaters, coats, scarves, helmets, headphones, pillows, or stuffed animals.
While the FDA has recognized products for the treatment of head lice as safe and effective, it has not approved products for the prevention of head lice.
Do I need to see a doctor for head lice treatment?
Lice elimination does not generally require professional medical attention or a trip to the doctor. In fact, RID® products enable you to provide safe and effective lice treatment at home. RID®, the market leader in head lice treatment products, has created the RID® Lice Treatment Complete Kit and RID® MAX Complete Lice Removal Kit to guide you through each of the steps. It includes scientifically proven products to kill lice, remove their eggs, and treat your home.
It is important to remember that, according to the CDC, for OTC treatments, a second treatment is often necessary to kill any newly hatched lice before they can produce new eggs.
Are all lice treatments the same?
There are 2 primary active ingredients in over-the-counter lice treatments—permethrin and pyrethrin-piperonyl butoxide. Permethrin (e.g., Nix) has been formulated to be effective after a single application, but conditioners and shampoos may impair its adherence to the hair shaft and reduce its residual effect. Therefore, a second treatment is recommended following an appropriate interval after the first if live lice are seen. Products with pyrethrin-piperonyl butoxide (e.g., RID) are designed for two applications, which is in line with expert recommendations for a two treatment approach.
Caution should be used when selecting non-drug lice treatments (e.g., herbals) as their efficacy has not been reviewed by the FDA. In addition, according to the CDC, there is no scientific evidence to determine if suffocation of head lice with mayonnaise, olive oil, margarine, butter or similar substances is an effective form of treatment.
How can I prevent head lice from coming back after treatment is complete?
Lice shampoo is designed to kill live lice, but unhatched eggs may still produce live lice. The newly hatched lice are not mature enough to reproduce and will be eliminated by repeating Step 1: Shampoo and Step 2: Comb-out 7-10 days after the first application of RID Lice Killing Shampoo.
You should also check other family members for head lice. If anyone in the family is infested, treat them by following the RID complete elimination process.
Where can I find head lice products in my store?
Head lice treatments, such as the RID® MAX Complete Lice Removal, can be found in your favorite store in the First Aid or Shampoo aisle.
What do I do with the comb when I'm done with one child?
The patented RID® Lice Comb is meant to be reused. To disinfect, soak it and any other combs and brushes in hot water above 130 degrees Fahrenheit for at least 10 minutes.
