Use Mr Nits Once-a-Week to ensure any headlice and live eggs are removed. This means you will keep on top of the problem and avoid getting the hard to remove dead eggs. The headlice life cycle is 7 to 10 days, so weekly application will help break the headlice cycle.

Mr Nits Once-a-Week contains high quality beneficial botanical oils. These are rich in the essential fatty acids that condition hair and provide nutrient support to hair and scalp.


Once a week apply enough to cover hair completely, without saturating. Most people find around 5ml to be suitable.
Comb with a long tooth metal comb to remove any lice/live eggs which might have appeared during the week.
Shampoo to rinse out then wet comb to remove any remaining lice/eggs.
To aid the removal of dead eggs and egg shells it is recommended to leave Mr Nits Once-a-Week in the hair for 10-20 minutes. The penetrating oils will help soften the eggs and make them easier to remove.
Fatty Acids
Vitamin E
Evening Primrose
