Frequently Asked

Answers to most common queries about Hedrin solution - head lice treatment in Malta.

What's special about Hedrin?
Instead of using an insecticide to poison the head lice Hedrin products kill them physically. Head lice do not produce urine, but eliminate excess water through their spiracles. Hedrin blocks this release route for the water, leading to the death of the louse.

Is Hedrin suitable to use on the whole family?
All products in the Hedrin range may be used in pregnancy* and on children as young as six months. Hedrin products do not contain any solvents that can cause problems in some asthma sufferers.
*Always talk to your doctor or pharmacist before taking any medicines in pregnancy

Can Hedrin be used on coloured or bleached hair?
Hedrin solution can be used with permanent hair dyes.

But with semi permanent and temporary hair dyes this may depend on the type of dye being used.

Cyclomethicone (the carrier in Hedrin solution) is used in a lot of shampoos and conditioners, but some non-permanent dyes may be affected.

It is best to apply to a small test area of hair first and wash out to check for compatibility or wait until the dye has washed naturally before commencing treatment. If in doubt consult your hairdresser with regard to the specific dyes being applied.

It is not advisable to use Hedrin solution directly before colouring or bleaching because it may prevent the colour taking to the hair.

Does Hedrin have a nasty odour?
No. Hedrin solution is a completely odourless, colourless silky lotion which spreads easily, making it simple to apply.

What about lice eggs?
If you are using Hedrin solution, in order to ensure that the lice are effectively eradicated, a second dose lotion should be applied seven days after the first treatment to deal with any eggs which may have hatched since the first application. The 'nits' (empty egg cases) are glued to the hair but are completely harmless. They can be removed with the fingers or a fine toothed comb.

Why repeat the treatment after 7 days and not after 2-3 days?
This ensures that any hatchlings from residual eggs are killed off. As per the life cycle of a louse, viable eggs that were left over after the first treatment will hatch in 7 days.

Do I have to comb the lice out?
Once the lice are killed they should wash or easily comb out of the hair - there is no need for a laborious combing regime. The empty egg cases or nits are glued to the hair shaft and can be removed with the fingers or a fine toothed comb if desired.

It is good practice to use a detection comb on a weekly basis to check for re-infection.

Why is there no lice comb in Hedrin-pack?
Combing is not a part of the Hedrin treatment regime.

Won't the head lice become resistant?
No. Because of the way Hedrin products work (by killing lice physically rather than by poisoning) lice cannot develop resistance to them — and they can still kill insecticide-resistant lice.

How often can I repeat the treatment?
If reinfestation occurs within a short period then Hedrin products may be used again straight away.

How much will I need?
A little Hedrin goes a long way. The amount needed depends entirely upon the length of hair to be treated. A 50ml bottle should be sufficient for a two-dose treatment of short hair. Longer hair or multiple treatments will require a larger bottle.

Is it OK to let it stay more than 8 hours?
Yes it is safe, but not best practice.

How do I get them out of my house? How must I treat the furniture?
Lice cannot survive off the head for more than a few hours. Hence environmental transmission is not considered to be a significant risk factor. Some countries such as the US do market insecticidal products to spray the house environment, furniture and bedding, but these are considered to be ineffective and could be argued to be an unnecessary use of insecticides in the environment.

Can I get lice if I lend my mobile phone to someone with head lice?

Do I have to put all our clothes in the freezer?

Do I have to tell the school?
Yes, if local regulations say that you need to.
