Heads bent purposefully together over the table are an encouraging sight, but one by-product is less welcome. The Lice Advisory Bureau, supported by the makers of Lyclear, offers on-line resources for parents and schools. A new PowerPoint presentation provides a straight-talking question-and-answer session covering such matters as what lice and nits are, how we get and know if we’ve got them, and how to kill them. More detailed information is found on the website. The presentation and other resources can be downloaded at: www.headliceadvice.netteachersdownloads.html
