Headlice Eggs (Nits) are and evolutionary masterpiece... waterproof, extremely tough and resilient.

The Nit Eggs have multiple Spiracles on the cap of the egg shell allowing a growing louse the ability to breathe whilst in the egg. Like a chicken egg the louse begins its life as a fertilised liquid.. in fact once mating act results in all 30 or so eggs within the breeding female louse being fertilised all at once.  She then lives for about another thirty days laying her little bundles at around 3-4 a day. 

Why repeat headlice treatments after seven days?

The louse within the nit egg, once old enough, can open and close the breathing spiracles as required and therefore they can survive being submerged in water, hair products such as shampoos and conditioners and even head lice treatments. 

This is why it is so important to repeat headlice treatments again after seven days in warmer weather and fourteen days in cooler climates, giving the little louse time to hatch, so you can catch the little sucker before it gets a chance to grow into a fully breeding adult louse. 



Never use Water-based product to remove headlice eggs.

Schools often send notes home instructing parents to comb the hair with conditioner to inspect for headlice. Although well meaning, this advice is not as helpful as it is intended to be.

Water-based product will swell human hair 15% within 2 minutes making the lice eggs more difficult to remove.

Oil-based products will not swell the hairshaft and are transparent making it much easier to identify the live lice and much easier to remove lice and thier nit eggs from the hair.


Oil-based Are the Best Headlice Treatments

Oil-based Headlice combing solution and headlice treatments are the best choice for detecting and eradicating headlice.

Any oil will suffocate the live lice and the oil will help support the easy release of the lice nit eggs.


Why are nit eggs so tough to remove

The nit eggs are glued to the hairsaft by a liquid chitisan. Chitisan is the same natural material as the shell of a beetle, so once it dries and hardens it forms a permanent casing around the hair fibre.

Only sliding the casing up the hairshaft will allow it to be removed.

Nit Ninja Nit Picker Pre-Shampoo Combing Oil is formulated to penetrate beneath the tough shell structure and lubricate the hair fibre to allow for effortless removal of the egg.
