rid-lice-treatmentThere are many over the counter products and head lice shampoos to treat head lice. If you are looking for a tradename lotion treatment for head lice, you’ll probably have the option to use RID lice killing shampoo.

Does it work? Is it safe? Here are some important points you should know.

What is RID head lice treatment exactly and does it work?

RID head lice treatment comprises 3 steps with one different product for each step:

Step 1 is the actual treatment, with RID lice killing shampoo. This will kill adult lice and nits.

Step 2 is the removal of head lice eggs or nits, with RID Lice & Egg Comb-Out Kit.

Step 3 is for control of head lice, with RID Home Lice Control Spray, to put on furniture, bedding, and non-washable items.

  • RID lice killing shampoo:

The active ingredients are Pyrethrum extract (equivalent to 0.33% pyrethrins) and piperonyl butoxide (4%). Pyrethrum is the name of a natural insecticide made from the dried flower heads of chrysanthemum. As such, it is not very effective to kill head lice, and this is why it is usually combined with piperonyl butoxide, which is a pesticide synergist that enhances the toxicity of pyrethrum to insects.

Pyrethrum has been used for centuries as an insecticide and a lice remedy in many countries, such as Persia in the Middle East. It works on head lice because, just like permethrins, it acts on their nervous system and causes paralysis and death. And piperonyl butoxide is used to make sure that the insects really die and are not only paralyzed.

The lice killing shampoo will enable you to kill adult lice and nymphs, but not head lice eggs. These have to be killed by other means or/and removed manually with a good nit comb.

  • RID Lice & Egg Comb-Out Kit:

As far as head lice eggs are concerned, the RID kit is a gel that contains glycerin and a nit comb, and this will help you comb dead nits out, but not kill them.

There are many reports that the RID treatment didn’t work, and in many cases this is because it was not applied properly, so make sure you always follow the directions carefully. There are also many studies and reports of resistant head lice to pyrethrum and pyrethroids in many western countries, which could be another reason why the treatment would not work.

Is RID lice shampoo safe to use?

There are a lot of safety informations on the RID official website, and there are many warnings so you should definitely pay attention to this. Pyrethrum is not harmless to health although it is not toxic for humans at low concentrations.

Pyrethroids are toxic to fish and other aquatic organisms, and to humans only at extremely high concentrations (this is not the case in head lice shampoos). However, they can have a range of side-effects from benign to severe, and this is why you should always think twice and take precautions before using such products.

You should not use RID head lice shampoo near the eyes, inside the nose, mouth, or vagina, in eyebrows or eyelashes, or if you are allergic to ragweed. It may cause breathing difficulty, an asthmatic attack, eye irritation, skin or scalp irritation. Scalp itching or redness may occur in any case.

Repeated exposure to pyrethrum may increase health risks even at lower concentrations, so you should not apply RID lice killing shampoo more than twice if you see no results. And you should not use the product on children younger than 2 or on pregnant or breast-feeding women.
