Head lice can be awkward to treat due to the time-consuming and precise nature of treatment and high re-infestation rate.
The insecticide products that were used to treat lice infestations have largely replaced with silicone and oil-based preparations which have a physical rather than a chemical action.
After a head lice infestation has been confirmed you can treat the lice at home by wet combing the hair with a head lice comb or by using a lotion or spray that’s designed to kill head lice.
However, neither will protect against re-infestation if head-to-head contact is made with someone with head lice during the treatment period.
You can get a fine toothed comb suitable for wet combing from your local pharmacy. Your pharmacist will also be able to recommend an over-the-counter lotion or spray and advise you about how to use it correctly if this is your preferred option.
