Do head lice spread in clothes, hats etc?
A head louse could be transferred by a hat or scarf but this is a very minor transmission risk. They have to be on humans to survive so they are highly unlikely to make the mistake of climbing onto anything other than another head in the first place! Anything other than a head generally means death to a head louse. Obviously you can avoid this risk by not sharing hats and brushes tc but it is not a huge risk in the first place.
