Hedrin Once Spray Gel

A pesticide-free head lice treatment that works in just 15 minutes. The dimeticone coats lice and their eggs and stops them breathing, so lice cannot become resistant to it. How to use: Spray onto dry hair until it is soaked from root to tip. Leave for 15 minutes, then shampoo out and comb through with a nit comb. Repeat after 7 days if needed. Good to know: Check everyone in the household and only treat those with live lice. Keep away from the eyes and from naked flames.
