The “Full Marks” brand, known for head lice treatment products, is currently owned by the multinational consumer goods company Reckitt Benckiser (formerly SSL International plc).

Description of the “Full Marks” Brand & Product Manufacturer

The “Full Marks” brand is primarily associated with over-the-counter head lice and egg elimination treatments.

Owner:
The brand is owned by Reckitt Benckiser Healthcare (UK) Limited, a major global producer of health, hygiene, and nutrition products (e.g., Durex, Scholl, Lysol). The brand was previously owned by SSL International plc before its acquisition by Reckitt in 2010.

Product Type:
The products are liquid solutions and sprays designed for treating head lice infestations and eliminating eggs.

Mode of Action:
Unlike traditional insecticide-based treatments that poison the lice, Full Marks solutions use a physical mode of action. The active ingredients, cyclomethicone and isopropyl myristate, coat the lice and cause them to dehydrate and die. This method means lice are less likely to develop resistance.

Product Features:

Pesticide-Free:
Contains no traditional pesticides, making it a non-toxic option.

Fast & Effective:
Clinically proven to be effective and typically requires only a 5 to 10-minute application time.

Included Accessories:
Each package typically includes a fine-toothed metal comb for removing dead lice and eggs after treatment.

Country of Origin:
The solution is typically made in Greece, while the comb is often made in the UK from local and imported components.
Summary

The “Full Marks” brand is a well-known name in over-the-counter healthcare, specifically in the UK and Europe, providing effective, non-insecticidal head lice treatments manufactured and distributed under the corporate umbrella of Reckitt Benckiser.
