Neositrín is a specialized brand of hair hygiene and anti-parasitic treatments primarily focused on the eradication and prevention of head lice and nits. The brand is owned and distributed by STADA, a major pharmaceutical company. Neositrín products are designed to provide rapid, non-insecticide solutions for families, utilizing a mechanical mode of action to eliminate infestations.

Core Product Offerings

The Neositrín product line includes several variations tailored for treatment speed, prevention, and follow-up care:

Neositrín Spray Gel (Anti-Lice Treatment):
A revolutionary solution that eliminates 100% of lice and nits. It typically works in as little as 1 minute of application.

Neositrín Protect:
A preventative conditioning spray formulated with Activdiol to dehydrate and remove lice before an infestation can grow. It is designed for use during high-risk periods like the “back to school” season.

Neositrín Complementary Shampoo:
A specific shampoo designed to help remove the oily residue of the treatment gels, which are water-repellent.

Neositrín Pediculicide Spray:
A liquid formulation (4% Dimethicone) used for standard lice eradication.

Mechanism of Action

Unlike traditional chemical treatments, Neositrín works through a physical process rather than an insecticide-based one:

Isolating and Suffocating:
The primary ingredients, Dimethicone and Penetrol, act by completely covering the louse.

Dehydration:
The gel prevents the louse from breathing and eliminating fluid, leading to dehydration and death.

Nit Penetration:
The inclusion of Penetrol allows the product to penetrate and destroy nits (lice eggs), ensuring the entire life cycle is interrupted.

Safety and Compliance

Insecticide-Free:
All Neositrín products are free of insecticides, which prevents lice from developing resistance to the treatment.

Suitability:
The products are generally hypoallergenic and suitable for adults and children. Depending on the specific product, they can be used from 12 months of age and are safe for use during pregnancy.

Skin Absorption:
The formula acts only on the surface and does not penetrate the skin.

Application and Usage

Because the treatment gel is designed to repel water, special care must be taken during removal:

Direct Shampooing:
Apply regular shampoo directly to dry hair (without wetting it first) to break down the gel.

Massage and Rinse:
Thoroughly massage the shampoo and then rinse with water.

Mechanical Removal:
After washing, it is often recommended to use a micro-grooved nit comb to remove dead nits from damp hair.
