They lay eggs (more lice)
No, it's not a good environment for their eggs. With all the chemicals most people have in their hair such as: shampoos, perms, dyes, hairspray, gels, oils, and greases... along with combing and brushing your hair its not a good place for gnats to lay their eggs.
A common example of something that has hair but doesn't lay eggs is a mammal, such as a dog or a cat. Mammals give live birth instead of laying eggs. Their bodies are covered in hair or fur, which helps with insulation and protection. Other examples include humans and other mammals that possess hair.
The platypus and echidna are egg-laying mammals and thus have fur. Most reptiles also lay eggs.
This could be a trick question. No other animal lays eggs in human hair while that hair is still attached to a human head, but hair that falls off or is cut off and blows away in the wind may be collected by birds and incorporated into their nests, where they will lay their eggs.
If your hair is clean, lice crawl up into your hair and start to live in your hair (like a hotel) and lay eggs.
Bot flies lay their eggs on the horses hair, typically on the legs and sometimes on the undersides of the body where the horse will lick them off. Some other type of parasites will migrate from inside the horses body to lay their eggs outside of the anal sphincter where they can attach to the skin or hair there.
