head lice transmission takes place with extended, direct, head to head contact. Extended means a a minimum of 20-30 minutes. Not casual contact, such as a brief hug. Were this not the case we would see the whole family from thanksgiving dinner(sharing hugs, couches) in our office. We would see the whole baseball team(sharing helmets). We would see the whole drama club (sharing costumes, hairbrushes). Instead, the majority of our customers are girls between the ages of 7-12. Most commonly girls bring head lice into the home and spread it to other siblings and to 20% of mothers. We attribute this to the behavior of latency age girls (very cuddly), their longer hair, finer hair shafts, exponentially higher density of hair shafts (children have finer hair and 10x as many hair shafts per cm2 as adults), and warmer scalps (children have slightly warmer scalps than adults). In addition, we as a society, put children together with other children for 4-8 hours/day. This all adds up to making children’s scalps the perfect environment for the human head louse.

head lice transmission. It may be mathematically possible for a human head louse to survive in a laboratory setting for up to 48 hours. But that louse immediately starts to become weak, hypothermic & dehydrated. Once off a scalp that louse is unable to navigate from an inanimate object back to the human scalp.
head lice transmission nits attached to “shed hairs” are not a way to contract head lice. When a nit is more than 1-2 inches away from the human scalp it is out of the range of temperature that supports incubation. Therefore incubation stops and the nit dies. Nymphs are needy, like premies. Were a nit to hatch on a shed hair off of the scalp, the hatched nymph would need an immediate blood meal. The nit would need to be able to lay directly on the scalp to maintain survivable body temperature. (when we look at the scalps of infested children, we see all of the nymphs lying directly on the scalp, as opposed to on the hair shafts). Neither of these requirements for survival will exist for a nit on a “shed hair”.
