Just had a message from DS's school saying they have detected another outbreak of head lice. Never having had this myself I don't really know what to look for. I couldn't see anything except for 1 tiny little 'thing' which jumped. It was sort of rice coloured and only one on its own. If this is not lice then how can I prevent him from getting it? Is there a natural way because I don't live in the UK and don't know what products are available here
