Full marks solution gets rid of head lice in just 5 minutes. Cyclomethicone (a silicone-based substance) and isopropyl myristate are the active ingredients and work by dissolving the outer coating of the head lice, which dehydrates and kills them.
They can then be removed along with any eggs using the Full Marks removal comb supplied.

Head lice cannot become resistant to Full marks because it works in this physical way, unlike conventional insecticides for head lice which poison the parasites by chemical means.

Ingredients

Cyclomethicone, Isopropyl Myristate

Usage and Instructions

3 simple steps to kill head lice and eliminate their eggs. For adults and children from 2 years.

Step 1 Detection

The only way to confirm a head lice infestation is by finding a live moving louse on the head. This can be done with the specially designed Full Marks Detector Comb. Weekly detection is recommended for ongoing prevention.

Step 2 Treatment

-First, comb through dry hair with a normal comb to remove any tangles. Shake the bottle and apply the solution to dry hair by applying the solution close to the root (Each application requires approximately 50ml of solution to treat a head lice infection on one head. However, you should apply enough to cover scalp and hair from root to tip. Long and/or thick hair may require more solution).
-Ensure the entire scalp and hair are fully coated with the solution.
-Massage in and leave on the hair for 5 minutes.

Remember, if someone in the household has head lice it is recommended that all members are checked as head lice are spread by close head to head contact. Treating everyone with head lice on the same day will minimise the chances of re-infestation.

Step 3 Removal

-After 5 minutes comb through the hair using the fine metal toothed Full Marks Removal Comb provided to remove dead lice and any eggs.

Tip: To ensure a thorough job, divide the hair into four quarters and comb each quarter separately. Take a small section of hair from the quarter; place the teeth of the comb as close as you can to the scalp and comb downwards away from the head to the tips of the hair.

After each stroke, rinse the comb to remove any hair, lice and eggs and wipe it on a tissue. Once an area of hair is free of lice and eggs push it to one side and continue until the quarter is completely clear.

Once you have finished the treatment, wash out the solution using an ordinary non-conditioning shampoo. Conditioner is not necessary. It may be necessary to wash the hair a couple of times to completely remove the solution.

It's a good idea to repeat the treatment after seven days to be sure that any lice emerging from eggs that survived the first treatment are killed.
