What Is Full Marks Solution?

Full Marks Solution is a quick and easy-to-use head lice treatment that kills head lice and helps remove them from the hair in just 5 minutes. Unlike traditional insecticide-based treatments, it uses a physical action to kill lice, making it suitable even for those with sensitive skin.

The solution contains cyclomethicone and isopropyl myristate, which coat and dehydrate the lice. It is suitable for adults and children over 2 years of age.

How Does Full Marks Solution Work?

Full Marks Solution works by physically coating head lice and disrupting their ability to regulate water, causing them to dehydrate and die. It does not use any pesticides or chemicals that lice can become resistant to, making it an effective choice even if other treatments have failed.

How to Use Full Marks Solution

Using Full Marks is simple and takes just a few minutes:

  • Apply the solution generously to dry hair, covering the scalp and entire length of the hair.
  • Massage in and leave for 5 minutes.
  • Use the included fine-tooth comb to remove dead lice and eggs (nits).
  • Shampoo thoroughly to wash out the product.

A second treatment is recommended after 7 days to catch any newly hatched lice.

How Many Bottles Will I Need?

The amount of Full Marks Solution you need depends on the length and thickness of the hair:

  • Short hair: One 100ml bottle may be enough for one application.
  • Medium to long hair: May require 150ml or more per treatment.
  • Always ensure full coverage for the treatment to be effective.

Since two applications are needed (the second after 7 days), consider buying enough solution for both treatments when purchasing.

Who Can Use Full Marks?

Full Marks Solution is suitable for adults and children aged 2 and above. It is not recommended for children under 2 years or for use on broken or irritated skin. Pregnant and breastfeeding women should consult a pharmacist before use.

Side Effects and Precautions

Full Marks is generally well tolerated. Side effects are uncommon but may include:

  • Itching or redness of the scalp
  • Greasy or oily hair after application
  • Mild irritation if it comes into contact with the eyes

Avoid contact with eyes and wash hands thoroughly after use. If you experience any serious side effects, stop using the product and seek medical advice.
