Water will swell the hairshaft making it harder to remove headlice nit eggs

Wet hair or water based products used on the hair will make it more difficult to remove the nit eggs from the hair.

Never use water based products when trying to remove headlice eggs.

How To Get Rid Of Nits

Headlice eggs (nits) are a small, light-brown to greyish-white, oval shaped pod that are glued at an angle to the side of the hair shaft. 

When the nit-egg are occupied by a louse they are darker in colour. Once the louse has hatched the nit-egg is a silver white colour... effectively the white nits are empty shells and the brow nits are still hosting a head louse.  

Nits are glued tightly to the hair... and must be manually removed by using a fine-toothed comb or by pinching and dragging them with your fingernail tips. 

The head louse develops inside the egg for 7 to 10 days in warm climates and up to 30 days in cooler climates. A breeding female louse will lay approximately 3-4 eggs per day for her normal breeding lifespan
of approximately 30 days. Therefore, one female could be responsible for producing more than 100 offspring.

Lice eggs need 35°C and 45% humidity to incubate their freshly laid nit eggs.

Freshly laid nit eggs will nearly always be within a few millimetres from the scalp as they need the heat of the body to incubate. In humid, warm climates lice will lay eggs all over the hair shaft, however in dry and cold climates they will lay almost entirely behind the ears and in the lower nape of a kids head. 

If you find silver-white nits at a distance of greater than two centimetres from the scalp then they are very most likely to be old hatched shells. Although these old nit-shells do not pose a risk of headlice, they are unsightly and should be removed. As the glue used by headlice to stick nits to the hair almost always totally encircles the hair shaft like a wedding ring, it is important to slide the nit eggs upwards along the hair shaft in order to remove them. 

The nature of adhesive and the way it rings the hair shaft makes the nit eggs extremely difficult to remove if the hair is wet with water. Water swells hair around 15% within 2.5 minutes thereby locking the adhesive very firmly in place. This means that dry nit picking is more successful than wet nit picking... or only use oils to aid in the removal of lice and their nit eggs as oil is non-polar and will not swell the hair fibre.  

Hatchlings are about 0.5mm in size and can grow up to 4mm in size. The hatchlings are extremely difficult to see with the naked eye, so if you spot a big headlouse in the hair, there is a strong chance she is an egg laying female. It is therefore very important to remove the larger lice from the hair as you remove the nits.  


Do not use water-based products to remove nits! 

A: Water swells the hair fiber up to 15% larger within 2.5 minutes... trapping the nit eggs tighter on the hair shaft.

B: The glue that lice use to glue the nit to the hair will not give if the hair shaft is wet.

C: Remove the nit-eggs effortlessly with Nit Picker Pre-shampoo Combing Oil...

D: Nit Picker Pre-shampoo Combing Oil is pure plant essential essences that will not swell the hair fibre and is able to lubricate between the egg glue and the hair shaft.

Combing with a fine toothed comb or using fingernails and Nit Picker will help the nits slide off the hair.
