What is Hedrin Once

Hedrin Once Spray Gel is a fast-acting solution for lice eggs and head lice. It contains dimeticone as an active ingredient which seals in the lice that is attached to the hair shaft, thus preventing movement. Owing to hunger the lice die in place. Penetrol is also another ingredient which helps the lice eggs penetrate.

How does Hedrin Once spray gel work? 

Hedrin Once Spray is a gel that comes in a spray format to help you get the medication on the affected areas generously. The treatment works by smothering the lice, which attach themselves on the hair shaft, making it difficult to kill them by use of water only. After 15 minutes upon application, you can wash your hair with shampoo, rinse and condition as desired.

This medication can be reused as often as needed without the lice becoming resistant to it. 

It is for external use only, and it should not be applied to infants under six months.
