I have been asked to reply.
The Department has produced a leaflet containing guidance on the prevention and treatment of head lice, which includes the option of using lotions as well as combing. The leaflet is widely available from locations that include schools and general practioners’ surgeries and on the Department’s website at:

A copy of the leaflet has been placed in the Library.
