Head lice are one of the things many parents worry about when their children return to school, with one in three youngsters in the UK affected at some point in the year.
They are spread by head-to-head contact and while not necessarily harmful, they can cause embarrassment and itching.
Treatments for head lice cannot prevent infection and should only be used when an infestation has been confirmed in order to avoid resistance. Infestation can be confirmed using a fine toothcomb to detect lice and their eggs.
A number of head lice lotions and sprays are available from pharmacists to kill head lice and their eggs and wet combing can also help. Speak to your GP or another healthcare professional if the problem persists.
