Pyrethrin-based lice treatments like Rid®, Pronto®, R&C®, Triple X®, and A-200® are designed to kill lice within 10 minutes when applied correctly.
These over-the-counter medications contain pyrethrins, which are natural insecticides derived from chrysanthemum flowers. They work by paralyzing the lice, leading to their death. However, it's crucial to understand that these products primarily kill live lice, not the nits (lice eggs).
Here's a breakdown of how these treatments typically work:
-
Application: Apply the medication to dry hair, ensuring complete coverage from the scalp to the ends of the hair.
-
Timing: Leave the medication in the hair for exactly 10 minutes (or as instructed on the product label). Do not exceed the recommended time, as it can cause skin irritation.
-
Rinsing: Rinse the hair thoroughly with water.
-
Combing: After treatment, use a fine-toothed nit comb to remove dead lice and nits from the hair. This step is essential, as the pyrethrin products don't reliably kill all nits.
-
Retreatment: Because nits can survive, a second treatment is usually recommended 7-10 days after the first to kill any newly hatched lice.
Important Considerations:
-
Resistance: Lice in some areas have developed resistance to pyrethrins. If the treatment does not seem effective, consult a doctor or pharmacist about alternative treatments.
-
Safety: Always follow the product instructions carefully. Pyrethrin-based products are generally safe when used as directed, but some people may experience skin irritation. Consult a doctor before use if you are pregnant, breastfeeding, or have allergies.
-
Nit Removal: Remember that killing the live lice is only part of the battle. Diligent nit removal with a nit comb is essential to prevent re-infestation.
-
Environmental Control: Wash bedding, clothing, and other items that may have come into contact with lice in hot water and dry them on high heat. Vacuum carpets and upholstered furniture.
