About Full Marks Head Lice Solution

Full Marks Head Lice Solution is a clinically proven treatment used to eliminate head lice and their eggs. It contains cyclomethicone and isopropyl myristate, which work by physically coating the lice, causing them to dehydrate and die. Because it has a physical action rather than a chemical one, there are no traditional pesticides involved. It also helps to loosen the eggs from the hair, making them easy to remove with the provided fine metal-toothed comb.

Full Marks Head Lice Solution is suitable for adults and children aged 2 years and over. A single bottle provides up to 4 treatments, depending on hair length and thickness:

What Is Full Marks Head Lice Solution Used For?

Full Marks Head Lice Solution is used to treat and eliminate head lice infestations and their eggs. It works through a physical mode of action—dehydrating the lice and loosening the nits from the hair shaft so they can be seamlessly combed out.

Who Is Full Marks Head Lice Solution Suitable For?

Full Marks is suitable for adults and children aged 2 years and over. Because it is free from traditional chemical pesticides, it is generally suitable for those who suffer from asthma and eczema.

Do not use Full Marks Head Lice Solution if you:

  • Are allergic to cyclomethicone, isopropyl myristate, or any other listed ingredients
  • Are treating a child under 2 years old

Speak to a healthcare professional before use if you:

  • Are pregnant or breastfeeding
  • Have a pre-existing severe skin or scalp condition

How to Use Full Marks Head Lice Solution

  1. Comb through dry hair with a normal comb to remove any tangles.
  2. Shake the bottle well and apply the solution directly to dry hair, close to the roots. Massage in thoroughly to completely cover the scalp and hair.
  3. Leave the solution on for exactly 5 minutes.
  4. Section the hair carefully. Comb from root to tip using the fine-toothed Full Marks Removal Comb provided to remove dead lice and eggs.
  5. Wash the hair using a normal, non-conditioning shampoo (you may need to shampoo twice to fully remove the solution) and rinse thoroughly.

To break the lice life cycle, you must repeat the treatment on Day 7, and again on Day 14 if necessary, to eradicate any newly hatched lice.

Possible Side Effects of Full Marks Head Lice Solution

Because Full Marks has a physical action rather than a chemical pesticide, side effects are rare.
Common side effects:

  • Temporary oily feel to the hair

Uncommon side effects:

  • Skin or scalp irritation
  • Eye irritation (if the product accidentally gets into the eyes)
  • Allergic reactions

Warnings and Precautions

  • Fire Hazard: Keep away from naked flames, cigarettes, and heat sources while the product is on the hair. Treated hair can easily catch fire.
  • For external use only. Do not swallow.
  • Avoid contact with eyes. If contact occurs, rinse immediately and thoroughly with warm water.
  • Clean up any spillages immediately, as the solution can cause floors and surfaces to become dangerously slippery.

Storage Instructions

  • Store below 25°C.
  • Keep the bottle tightly capped.
  • Keep out of the sight and reach of children.
  • Store away from naked flames and heat sources.
