Product overview
About Hedrin Once Spray Gel
Head lice in a single treatment: Hedrin Once's spray gel kills lice and eggs in one 15-minute application — the penetrol-boosted dimeticone gets into eggs that ordinary treatments wait a week to catch as hatchlings. Clinically tested on real heads. 100ml.
One treatment, honestly assessed
Because it kills eggs as well as lice, Hedrin Once is designed not to need the day-7 repeat — the main way lice treatments fail. The trade: a 15-minute wait and a gel texture that wants a thorough rinse. Fair exchange for one evening instead of two.
How to use
Spray onto dry hair until saturated, work in to coat every strand, leave 15 minutes, then rinse thoroughly and comb. Check with a detection comb a few days later.
Good to know
Still check the whole household the same day — one treated head in an untreated house is a revolving door. Physical action means no insecticide resistance.

Frequently asked questions
Why doesn't this need a second treatment?
The penetrol helps dimeticone penetrate the eggs, killing them before they hatch — which is the whole reason repeats normally exist.
How long does it take?
Saturate dry hair, wait 15 minutes, rinse well, comb. One evening.
Should I still check afterwards?
Yes — detection-comb a few days later, and check the household the day you treat.
