They are happy to make their home on all kinds of heads. Hair can be clean or dirty, straight or curly, light or dark. Children of both sexes are just as likely to be affected as parents, carers, grandparents and teachers. Head lice show no preference, all they want is a warm human head to call home. Interestingly, they cannot live on other hairy parts of the human body and will not live and breed in bedding, towels or other soft furnishings. There is no need to disinfect your home. Your pets are safe from infestation too – head lice only like humans!
