What’s special about Hedrin?
Instead of using an insecticide to poison the head lice, Hedrin products kill them physically
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 or using medical devices in pregnancy.
Can Hedrin be used on coloured or bleached hair?
With permanent, semi- permanent and temporary hair dyes this may depend on the type of dye being used.
Dimeticone (the active ingredient) and Cyclomethicone (the carrier in Hedrin solution) are 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 directly before colouring or bleaching because it may prevent the colour taking to the hair.
Does Hedrin have a nasty odour?
No. Hedrin is a completely odourless, colourless silky lotion which spreads easily, making it simple to apply.
What about lice eggs?
Hedrin has been clinically tested to kill lice and eggs in one go. If you are using Hedrin 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 empty egg cases are glued to the hair but are completely harmless.
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.
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 7 days after treatment.
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 100ml bottle should be sufficient dose a four-dose treatment of short hair. Longer hair or multiple treatments will require a larger bottle.
Is there a way to protect against head lice?
There are various home remedies that people claim can repel head lice and help prevent infection, but evidence to support how effective they are is very limited.
What happens if I accidentally spill some product?
Hedrin Solution and Hedrin Once treatments are silicone based and care should be taken with accidental spills as these can cause a slip hazard.
Spillages on hard surfaces can be cleaned using a clean dry cloth or paper towel to absorb the spill and then any oily residue removed cleaned using neat detergent.
If the product is spilled onto clothing, blot any excess with a clean cloth or paper and then either use a proprietary grease/oil stain remover or alternatively rub neat detergent or washing up liquid into the affected area. Leave to soak for an hour or so then launder as normal.
