Can you use Hedrin Once on coloured hair?
Hedrin Once has not been tested for use on permanent, semi-permanent or temporary hair dyes. We recommend applying the formula to a small test area of hair before commencing treatment. If in doubt you can always consult a hairdresser. It is not advisable to use Hedrin Once directly before colouring or bleaching because it may prevent the colour taking to the hair.
Can you use Hedrin Once on hair extensions?
Hedrin Once has not been tested for use on hair extensions meaning it’s difficult to know whether products will affect them. Hair extensions could block products from coming into contact with head lice, but not necessarily though. If in doubt consult a hairdresser.
Can you use Hedrin Once on beards?
Hedrin Once has not been tested on beards as its intended purpose is for application on hair and scalp. However, so long as the application comes into contact with head lice or eggs, it should fulfil its intended use.
After using Hedrin Once are eggs still on the hair?
If the correct process has been followed when using Hedrin Once, eggs should not still be on the hair after use. When working the solution into the hair, it is recommended to use fingers or a comb to remove head lice and eggs.
What age can I use Hedrin Once?
Hedrin Once is suitable for adults and children 6 months and over.
