How Natroba™ (Spinosad) works

A prescription head lice medicine, FDA-approved for adults and children 6 months and older.

  • Leaf Icon
    A naturally derived active ingredient.

    Spinosad comes from a soil bacterium. You apply it topically for 10 minutes, then rinse.

  • Hair Comb icon
    It targets lice and their eggs where they live.

    Natroba™ eliminates both adult head lice and their nits in a single step.

  • Bug icon
    It works on the scalp, not in the body.

    Spinosad only targets the bugs, not the body. It is not absorbed into your skin.

Why one application is enough

Most head lice treatments miss the eggs, so they force you into repeat doses and hours of nit combing. Because Natroba™ kills the eggs too, most patients are head lice-free after one application, with no repeat dosing and no nit combing required.

And with over 98% of U.S. head lice now resistant to permethrin-based OTC products across 48 states, Natroba™ works even when those products fail.

Skip the lice clinic. Natroba™ works quickly at home.

No salon chair. No removal session. No nit combing required. The same single application, done in your own bathroom.
