Full Marks is a treatment for head lice and nits, designed to eliminate lice without the use of traditional insecticides. It contains isopropyl myristate and cyclomethicone, which work by dehydrating and suffocating the lice, making it effective in killing both lice and their eggs. Full Marks is easy to apply and comes with a fine-toothed comb to help remove dead lice and eggs from the hair after treatment. It's suitable for adults and children over the age of 2, providing a safe, non-toxic solution for treating head lice infestations.
