Information before and after appointments

Prior to treatment and screening

It is advisable to make an appointment a minimum of seven days after any head lice treatment has been applied, as in some cases this will make it very difficult to make an accurate diagnosis. Especially in early or light infestations

Hair needs to be tangle and knot free to make optimum time of the appointment.


The serum that is applied during treatment will need to be washed out at home.  There is no restrictions on time as the serum will have killed the lice and eggs during the treatment process.

It is recommended that to wash out the serum, it is best to use washing up liquid (for dishes in the sink) as this will wash the serum in the hair away quicker than standard shampoos. 

When applying the washing up liquid please massage in thoroughly for at least a minute, if the hair does not lather, apply a second application to the hair. Follow with normal shampoo and conditioner.

Please be very cautious after washing hair as it can make baths, showers and sinks a slip hazard.  Use a household cleaning product to clear away any residue before entering a shower, bath or anywhere that the serum may be.

Pillow cases, duvet covers and towels are advised to be put through a normal wash.

If soft toys are used put to one side out of the reach for forty eight hours


Preventing further infestations

Keep hair tied down, pony tails should be in the nape of the neck and not high on the head.  French plaits are a very good hairstyle to keep longer hair close to the head.  Buns are also a good hairstyle.

Do not share hairbrushes

In the winter keep hats and scarves in the sleeves of the coat while at school

Prevention sprays have very little evidence that they work, but if you do choose to use these products please re apply during the day as they tend to evaporate when heads get hot.

Try not to feel embarrassed about head lice they are a very common problem in schools and are the most likely thing your child will pick up after the common cold.  Being open with schools, friends and families will help your child not to get them back again.

Managing Expectations

It is very difficult to give a diagnosis without seeing the customer in person, every case of head lice is different.  Head lice - the live insect has four stages - 1,2 and 3 before puberty where the lice are very small and can be a reason for not being able to get rid of head lice.

Adult head lice are about 3mm long and are the easiest to kill and remove

Live head lice eggs - the most difficult to eliminate as they are often camouflaged as the egg that is full of fluid reflects the colour of the hair it is attached to.  

Nits - these are the empty shells left behind after the louse has hatched.  Though not very pleasant to look at they are harmless.  If heating devices and hair straighteners are used they become very difficult to remove as they are stuck tighter to the hair and are often flat on the hair.

During your appointment all live head lice and eggs will be killed.  During the first appointment every effort is made to remove as many nits (harmless as non viable shells) as possible. It will depend mainly on quantity and condition of nits.  

On the follow up appointment before applying the second serum treatment we will assess if further combing is needed to remove harmless non viable shells.


At NitNOT we understand the stress and anxiety that head lice can bring to a family.  Our guarantee is simple.

As long as the person treated has had the first and the follow up appointment no more than ten days apart.  If an infestation is found in the following two weeks we will at no extra charge apply a serum treatment to the head.

If we believe that this is a re-infestation we would kindly request that other family members are checked at the same time. To ensure that it is not being spread within the home.  Please be assured we do not refuse to apply treatment if not all family members can attend.  But without measure it may mean you family will be passing it to each other.
