What is Hedrin 4% Lotion Spray?

Hedrin 4% Lotion Spray is a treatment for the infestation of head lice. This treatment works thanks to the active ingredient which is dimeticone. Dimeticone works by covering and drowning the head lice and preventing them from moving. Unlike other forms of head lice treatment, this spray will not poison them, so they cannot become immune to it.


What causes head lice?

Head lice can spread, and do so because of contact between people and their heads. They can also spread because of sharing items such as combs, brushes, hats, and headphones. They can also spread due to fabrics and also bedding and fabric on furniture. Head lice do not end up on hair due to poor hygiene.


Who is this lotion suitable for?

This lotion spray can be used by adults and children aged from 6 months and over. For any child younger than 6 months, speak to a doctor for advice. It should not be used by anyone who is allergic to the ingredients contained in the spray. This spray is safe to use when using other types of medication.


Can someone who is pregnant or breastfeeding use this spray?

This Hedrin Lotion Spray is safe to use when pregnant or breastfeeding. Though anyone who does need this treatment should speak to a medical professional for advice before using.


How should Hedrin 4% Lotion Spray be used?

Before using, cover the shoulders with a towel. Be careful not to spray on fabrics as it can discolour them. Do not spray on the eyes and not breathe in when using. Hold the spray about 10cm from the hair and spray onto dry hair. Ensure that the scalp is effectively covered with the spray. Once applied, work through the hair and scalp with the fingers and a comb. Allow the hair to dry naturally. Leave the solution on the hair for 8 hours, or on overnight. Wash the hair normally afterwards. Apply the solution again after 7 days of use. This is important as eggs will not be treated with this spray.


Are there any side effects?

Like with many types of medication, there is a chance of side effects, potential side effects include:
