Unlike traditional head lice treatments which poison the lice, Full Marks Solution has a physical action on the lice causing them to dehydrate (lose water) and die, they can then be removed along with any eggs using the comb provided. One sixth (approx 50ml) of this bottle should contain sufficient solution to treat a head lice infection on one head. However, you should apply enough to cover scalp and hair to ensure complete success.
