About Hedrin
Hedrin is a leading head lice treatment brand, using a physical (dimeticone) action rather than traditional pesticides to get rid of head lice. Because it works physically, lice cannot build up resistance to it.
The range includes Hedrin Once, Treat & Go, All in One, and lotion and spray formats, plus combs.
Browse the Hedrin range below, dispatched from our UK pharmacy. Always read the label, treat everyone affected in the household, and check the whole family for lice.
Frequently asked questions
Does Hedrin kill lice eggs?
Hedrin kills head lice, and some products are designed to help kill eggs too, but eggs are tough, so a second treatment after 7 days is usually recommended to catch any lice that hatch in the meantime. Combing through with a fine-toothed nit comb helps remove eggs and dead lice.
How does Hedrin work?
Hedrin's dimeticone coats the lice and blocks their breathing and water balance, physically killing them rather than poisoning them like older pesticide treatments. Because of this physical action, head lice cannot become resistant to it.
How do you use Hedrin?
Apply it to dry hair, making sure the whole scalp and all the hair is covered, leave it on for the time stated on your product (some are left on longer, even overnight), then wash it out and comb through. Follow the specific pack, and repeat after 7 days if advised.
Can you use Hedrin when pregnant?
Because Hedrin works physically and very little is absorbed, it is generally considered a suitable option during pregnancy and breastfeeding, but it is best to check with your pharmacist or midwife. They can confirm the right product for you.
Can you use Hedrin on coloured hair?
Yes, Hedrin is generally fine to use on coloured or treated hair as it works physically rather than chemically. As always, follow the instructions and rinse it out thoroughly.
Can you use Hedrin on a dog or cat?
No - Hedrin is made to treat human head lice and should not be used on pets, which get different parasites needing different, animal-specific treatments. Speak to your vet if your pet has a problem with fleas or other parasites.
