Product overview

About Hedrin 4% Lotion

Head lice treatment that works by physics, not poison: Hedrin's 4% dimeticone lotion coats lice in a silicone film that immobilises and kills them — no organophosphate insecticides, no chemical resistance for lice to evolve, no pesticide smell. Clinically proven, skin-friendly, odourless, and calm enough for routine family use. 50ml.

Why dimeticone beat the old insecticides

Decades of insecticide shampoos bred resistant lice. Dimeticone sidesteps the arms race entirely — it physically seals the louse, which no mutation can dodge. That's why physical treatments are now the first-line NHS-endorsed approach, especially for children's heads that see repeat infestations every school term.

How to use

Apply to dry hair, coating scalp to tips thoroughly. Leave for 8 hours (overnight is easiest), then wash out. Repeat after 7 days to catch lice hatching from surviving eggs — the second dose is not optional. Comb out with a detection comb between doses.

Good to know

Check the whole household's heads and treat everyone with live lice the same day — lice commute between family members. Suitable from 6 months; fine for asthma sufferers and sensitive skins where insecticides aren't.
