## Description

Product Description A fast acting solution that takes just 15 minutes to work A thicker gel formulation which contains Penetrol to aid the penetration of the louse egg Fast acting to shorten treatment time Clinically proven to kill head lice and eggs with just one application. Hedrin Once Liquid Gel has been specially formulated with non-volatile ingredients. However, normal safety precautions should be observed. Hair and clothing should always be kept away from naked flames and other sources of ignition. If a member of the family has live head lice, check other family members and treat all other cases of live head lice, which are discovered at the same time. The spray comes ready assembled. Before use, remove the coloured safety clip from under the spray nozzle. This may be retained or disposed of safely. Cover the shoulders with a towel. How to use it: - SHAKE THE BOTTLE WELL BEFORE USE Holding the spray approximately 10cm from the hair carefully spray sufficient gel evenly over dry hair, to ensure the scalp and hair are fully covered and the hair is SATURATED. Be careful not to spray into eyes and face and do not breathe the spray. - Work into hair with the fingers or an ordinary comb spreading the gel thoroughly and evenly from root to tips.- Leave hair for at least 15 minutes (or longer if more convenient). - Apply shampoo directly to the entire surface of the hair without first wetting, shampoo thoroughly then rinse with water.- Repeat process, and then apply conditioner, rinse and dry. Hedrin Once Spray Gel contains anti-foaming ingredients so the shampoo will not lather readily. If necessary, repeat the whole procedure remembering to apply shampoo directly to dry hair.
