Head lice are usually spread among children (sometimes even in adults) crowded together in urban daycare centres and primary schools.
In this way, they travel by direct head to head contact when children play with their heads close together or indirectly through sharing hats, coat hooks, scarves, bike helmets, headphones, hairbrushes, toys, or bedding.
Poor hair and scalp hygiene does play a huge role in causing head lice and may become worse if it’s left untreated
