Always read the full pack instructions before you start. Begin by shampooing any head lice treatment out of the hair. For towel dried hair and dry hair, spray on Hedrin Prevent Lice and comb through. Leave to dry naturally or use a hair dryer if preferred. Use at least twice a week for the best protection against head lice.

Hedrin Prevent Lice Spray is combined with a leave in conditioner designed to stop a head lice infestation. For best results use as part of a daily routine or at least twice a week.

Hedrin Prevent Lice is not a treatment product. It has been designed to protect against cases of head lice.

Hedrin Prevent Lice contains octane 1,2-diol, PEG-6 caprylic/capric glycerides, PEG-12 dimethicone, carbomer, sodium hydroxide, fragrance (contains limonene) and water.

Hedrin Prevent Lice should be used as part of a daily routine or at least twice a week to help protect against head lice.

Hedrin Prevent Lice is unlikely to cause any ill effects to pregnancy or breastfeeding if used as directed. However, if you’re unsure consult a doctor or pharmacist. 

Hedrin Prevent Lice 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 Prevent Lice directly before colouring or bleaching because it may prevent the colour taking to the hair.

Hedrin Prevent Lice 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.

Hedrin Prevent Lice has not been tested on beards as its intended purpose is for application on hair and scalp. However, so long as the spray is applied to the desired area, it should fulfil its intended use.

Hedrin Prevent Lice is suitable for adults and children 6 months and over to use.
