A special "Bug Buster" comb, used with ordinary shampoo, can rid a child's hair of lice without recourse to possibly unsafe pesticides, according to a report in Shared Wisdom, the journal of Community Hygiene Concern. Using the comb twice a week for a fortnight breaks the lice's life cycle and leaves only harmless empty shells behind. For more details, call the Bug Buster Helpline: 0181-341-7167 (England).
