What to do if you find a living, moving louse.
Instead of using an insecticide to poison the head lice, Hedrin products kill them physically
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.
Hedrin 4% Lotion and Hedrin Once 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.
Dimeticone (the active ingredient) and Cyclomethicone (the carrier in Hedrin 4% lotion) 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 4% Lotion or Hedrin Once directly before colouring or bleaching because it may prevent the colour taking to the hair. Hedrin Treat & Go is water based and can be used both before and after colouring.
No. Hedrin 4% Lotion is a completely odourless, colourless silky lotion which spreads easily, making it simple to apply. Hedrin Once contains Penetrol® which gives it a faint pleasant perfume. Hedrin Treat & Go contains no added fragrance.
Hedrin Once has been clinically proven to kill lice and eggs in one go. If you are using Hedrin 4% Lotion or Treat & Go, 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. Stubborn Egg Loosening Lotion can be used to help remove the eggs when doing so by comb or using your fingers.
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. Stubborn egg loosening lotion can be used to help with removal.
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.
If reinfestation occurs within a short period then Hedrin products may be used 7 days after treatment.
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.
Hedrin 4% Lotion (150ml and 120ml Spray) is available through pharmacies and pharmacy counters. The rest of the Hedrin range is available from pharmacies, pharmacy counters and medicine aisles in-store.
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. Hedrin Protect and Go is a conditioning spray (containing Activdiol 1%) clinically proven to help protect against head lice.
Hedrin 4% Lotion 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.
Hedrin Treat & Go and Protect and Go can be cleaned up with damp cloth and any affected clothing rinsed and washed as normal.
