Paranix Express Lotion is an anti-lice lotion containing isopropyl myristate that works by dehydrating the lice, without using insecticides. Effective against head lice, nymphs, and eggs, it kills lice quickly in 2 minutes and is used with a fine-toothed metal comb.
Paranix Express is an anti-lice lotion containing isopropyl myristate, propylene glycol monolaurate, and paraffin oil. Unlike anti-lice shampoos, it is applied undiluted to dry hair and works by dehydrating the lice: its oily formula dries them out. It comes with a fine-toothed metal comb.
The lotion is effective against head lice, nymphs, and eggs(known as nits), including “super lice”—lice that have become resistant to certain insecticides. Once the hair is thoroughly saturated, it kills the lice quickly within 2 minutes of application, before combing and shampooing.
Its mechanical mode of action does not involve any insecticides. Dermatologically tested, this treatment is designed to be gentle on the scalp and hair. The lotion remains easy to comb out, and does not leave the hair greasy after shampooing.
It’s ideal for the first few weeks of the school year, when lice alerts are common and you need to treat the hair without spending the entire evening on it. Such a short application time is one that a child will agree to sit through without complaining, and the entire treatment can be completed before the evening bath, including shampooing.
The final step requires a shampoo for oily hair. For this, we recommend Klorane Nettle Shampoo for Oily Hair: its cleansing formula, designed for hair that gets oily quickly, blends with the oily lotion when applied to dry hair, then washes it away during rinsing—where a mild shampoo would struggle to remove it.
Directions for Use
Shake the bottle, apply a sufficient amount of lotion to dry hair, and distribute it evenly from the roots to the ends, covering the entire hair and scalp, then let it sit for 2 minutes. Before washing the hair, comb through the wet hair with the fine-toothed metal comb provided, then apply a shampoo for oily hair directly to the hair without wetting it, add a little water, shampoo thoroughly, and rinse with lukewarm water.

Precautions
Ingredients
Isopropyl myristate, Propylene glycol monolaurate, Paraffinum liquidum, Benzyl alcohol.
Packaging
Box containing one bottle of lotion and one fine-toothed metal lice comb, both of which are medical devices. The 95-ml bottle provides up to 4 applications, and the 195-ml bottle provides up to 8 applications, depending on hair length.
At the counter, the most common reason for failure we hear is related to the amount used, not the product itself. On long or thick hair, applying the lotion sparingly leaves strands dry, allowing the lice hiding there to survive. It’s better to saturate the hair strand by strand, paying special attention to the nape of the neck and behind the ears, even if that means using up the bottle faster. When it comes to safety, the flammability risk is the most surprising precaution: it remains a concern right up until the final rinse.
The step most often done incorrectly is shampooing: when applied to dry hair and then emulsified with a little water, it removes the oily base, whereas hair that is wet first remains greasy. In the days that follow, a thorough comb-through of damp, detangled hair—every two or three days for about ten days—will indicate whether the treatment was sufficient.
Do I need to repeat the treatment with Paranix Express?
Not necessarily: in the manufacturer’s study, no live lice or nymphs were found after a single application. A second treatment may, however, be necessary in cases of severe infestation or reinfestation. This is done if live lice are found again, usually 7 to 10 days after the first treatment, to allow any surviving nits time to hatch. If live lice persist after two treatments, the pharmacist or doctor will recommend an alternative method.
Should the whole family be treated when a child uses Paranix Express?
Every member of the household is examined on the same day. Anyone found to have live lice is treated on the same day as the child, to prevent the lice from spreading from an untreated head to a treated one.
Should I wash the laundry and treat the house after using Paranix Express?
Laundry that has come into contact with the head in the preceding days (pillowcases, sheets, hats, scarves) should be washed at 60°C. Items that cannot be machine-washed, such as stuffed animals or helmets, can be kept isolated for three days in a sealed bag, and the combs should be cleaned with very hot water. It is not necessary to disinfect the home: away from the head, a louse survives for only one to two days.
Can my child return to school after treatment with Paranix Express?
Yes, staying home from school is not recommended once treatment is complete. Notifying the school allows other families to check their children’s hair and helps prevent lice from spreading back and forth in the classroom.
